The odds that a student who got an A on the exam got help from the professor during office hours is about 41.77%.

To solve this problem, we can use Bayes' theorem, which is a way to calculate conditional probabilities. Let A be the event that a student got an A on the exam, and B be the event that a student got help from the professor during office hours.

We want to find P(B|A), the probability that a student got help from the professor during office hours given that they got an A on the exam.

Bayes' theorem states that:

P(B|A) = P(A|B) * P(B) / P(A)

We are given that students who get help from the professor during office hours are 18 times more likely to get an A on the exam than students who do not get help, so:

P(A|B) = 18 * P(A|B')

where B' is the complement of B (i.e., not getting help from the professor during office hours).

We are also given that about 11.7% of students get help from the professor during office hours, so:

P(B) = 0.117

We can calculate P(A) by using the law of total probability:

P(A) = P(A|B) * P(B) + P(A|B') * P(B')

Since P(B') = 1 - P(B), we have:

P(A) = 18 * P(A|B') * 0.883 + P(A|B) * 0.117

Now we can plug in the values we have and solve for P(B|A):

P(B|A) = (18 * P(A|B') * P(B)) / (18 * P(A|B') * 0.883 + P(A|B) * 0.117)

Using a calculator, we can find that P(B|A) is approximately 41.77%.

In other words, if we randomly select a student who got an A on the exam, there is a 41.77% chance that they got help from the professor during office hours.

The cost of 5 electronic games falls between $165 and $285.

Mr. Keller bought 5 electronic games, and the games range from $25 to $65 for each game.

We need to find a reasonable estimate of the amount he paid for the games.

Let's find the average value of the games. Add up the cost of each game and divide by the number of games:

The amount for 5 games = (25 + 30 + 35 + 55 + 65) dollar

Amount for 5 games = 240 dollars

Therefore, we can say that the reasonable estimate of the amount he paid for the games is between $165 and $285 dollars. This is because the cost of 5 electronic games falls in between the given values. Hence, option (c) between $165 and $285 is the correct answer.

Option (c) is the correct option: between $165 and $285.

It is not possible that the intersection case is P(A B)=0.5 .

The set of all objects that are members of both sets A and B is represented by the intersection of the two sets A and B, abbreviated as A∩B.

If there is any element x that is an element of both A and B, then we can also say that A intersects (meets) B at x. If A∩B is an inhabited set, which means that there must be some x such that x∈A∩B exists, then A intersects B equivalently.

If A does not intersect B, then A and B are said to be disjoint. They share no elements, to put it simply. If the intersection of A and B contains nothing—A∩B=Ф—then A and B are disjoint.

Explanation:

The likelihood of occurring of an event is called probability.

Consider two events A and B are occurred with probabilities P(A) and P(B)  respectively.

The probability that both the events occurs is,

P(A and B)=P(A∩B)

When both the events are independent,

P(A and B)=P(AB) = P(A)x P(B)

The probability that either A or B occurs is,

P(A or B)= P(AUB) = P(A)+P(B)-P(A∩B)

When both the events are mutually exclusive the probability that either A or B occurs is,

P(A or B)=P(AUB) = P(A)+P(B)

The compliment of the probability is,

P(A)=1-P(A)

The conditional probability of occurring of an event A when it is given that B had already occurred is,

P(A|B)=P(A∩B)/P(B)

Let A represent the situation where the chosen person has a Visa credit card and B represent the situation where they have a Master card. The probability of occurring event A is 0.6 and the probability of occurring event B is 0.4 that is, P(A)=0.6, P(B)=0.4 .

It is known that P(A B)∠P(A) and P(A B)∠P(B) . So, it is not possible that the intersection case, P(A B)=0.5 .

Using a ruler and compasses, draw PQ (7.5cm), locate R using a 6.1cm radius from P, then connect PR. To measure ∠PQR, use a protractor with Q as the center.

To construct triangle PQR with sides PQ = 7.5 cm, QR = 6.1 cm, and ∠PQR = 45 degrees, follow these steps:

1. Draw a line segment PQ of length 7.5 cm using a ruler.

2. Place the compass at point P and draw an arc with a radius of 6.1 cm to intersect PQ. Label this point of intersection as R.

3. Set the compass to a radius of 7.5 cm and draw an arc with center Q.

4. Without changing the compass width, draw another arc with center R to intersect the previous arc. Label this point of intersection as P.

5. Connect points P and Q with a straight line segment to complete triangle PQR.

6. To measure the angle ∠PQR, use a protractor and place it on line segment QR such that the center of the protractor aligns with point Q. Then measure a 45-degree angle starting from the line segment QR and mark the point of intersection on line segment PQ. Label this point as S.

The probability of picking each kind of card is 1/4 or 0.25.

There are four kinds of cards in a standard deck of 52 cards: hearts, diamonds, clubs, and spades. Each kind has 13 cards (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King).

To find the probability of picking a card of each kind, we can use the following formula:

Probability = Number of favorable outcomes / Total number of outcomes

Probability of picking a heart:

There are 13 hearts in the deck, so the number of favorable outcomes is 13. The total number of outcomes is 52, since there are 52 cards in the deck. Therefore, the probability of picking a heart is:

Probability of picking a heart = 13/52

Probability of picking a heart = 1/4

Probability of picking a diamond:

There are 13 diamonds in the deck, so the number of favorable outcomes is 13. The total number of outcomes is still 52, since we haven't replaced the card that we picked earlier. Therefore, the probability of picking a diamond is:

Probability of picking a diamond = 13/52

Probability of picking a diamond = 1/4

Probability of picking a club:

There are 13 clubs in the deck, so the number of favorable outcomes is 13. The total number of outcomes is still 52. Therefore, the probability of picking a club is:

Probability of picking a club = 13/52

Probability of picking a club = 1/4

Probability of picking a spade:

There are 13 spades in the deck, so the number of favorable outcomes is 13. The total number of outcomes is still 52. Therefore, the probability of picking a spade is:

Probability of picking a spade = 13/52

Probability of picking a spade = 1/4

The three computations covered by the reliability factor table are sample size, index of reliability, and index of precision. Sample size deals with the size of the sample being used in order to achieve a desirable level of reliability.

Index of reliability is used to measure the consistency of results achieved over multiple trials. It does this by calculating the total number of items that contribute significantly to the final result. Finally, the index of precision measures the effect size of the sample, which is determined by comparing the results from the sample with the expected results.

The sample size computation gives the researcher an idea of the number of items that should be included in a sample in order to get the most reliable results. This is done by taking into account a number of factors including the variability of the population, the type of measurements used, and the desired level of accuracy.

The index of reliability is commonly calculated by finding the ratio of the number of items contributing significantly to the total result to the total number of items in the sample. This ratio is then multiplied by 100 in order to get a final score.
