It is known that 60% of the students at a large university have a job and 40% do not have a job. If three of these students are randomly selected what is the probability all three have jobs?
a. 0.360
b. 0.216
c. 0.648
d. 0.060

b. 0.216

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they have a job, or they do not. The probability of a student having a job is independent of other students. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

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

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

And p is the probability of X happening.

60% of the students at a large university have a job

This means that

If three of these students are randomly selected what is the probability all three have jobs?

This is when . So

So the correct answer is:

b. 0.216

no he doesnt because "-16' is negatiive

step-by-step explanation:

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
