In a survey of 300 college graduates, 53% reported that they entered a profession closely related to their college major. If 9 o

ExtremeBDS [4]

Answer:

0.1348 = 13.48% probability that 3 of them entered a profession closely related to their college major.

Step-by-step explanation:

For each graduate, there are only two possible outcomes. Either they entered a profession closely related to their college major, or they did not. The probability of a graduate entering a profession closely related to their college major is independent of other graduates. This, coupled with the fact that they are chosen with replacement, means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

53% reported that they entered a profession closely related to their college major.

This means that $p = 0.53$

9 of those survey subjects are randomly selected

This means that $n = 9$

What is the probability that 3 of them entered a profession closely related to their college major?

This is P(X = 3).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 9) = C_{9,3}.(0.53)^{3}.(0.47)^{6} = 0.1348$

0.1348 = 13.48% probability that 3 of them entered a profession closely related to their college major.

John Davis makes $9.75 an hour. He works four hours on Monday, six hours on Tuesday, five hours on Wednesday, five hours on Thur

Hatshy [7]

You are given John Davis’ rate which is $9.75 an hour. It is said that he works for four hours on Monday, six hours on Tuesday, five hours on Wednesday, five hours on Thursday, and seven hours on Friday. You are asked to find the gross pay of John Davis. All you need to do is to multiply the rate to the hour of work.

Monday: $9.75(4h) = $39
Tuesday: $9.75(6h) = $58.5
Wednesday: $9.75(5h) = $48.75
Thursday: $9.75(5h) = $48.75
Friday: $9.75(7h) = $68.25

To get the gross pay, add everything and you will get $263.25. The answer is letter D.
