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.

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.
53% reported that they entered a profession closely related to their college major.
This means that 
9 of those survey subjects are randomly selected
This means that 
What is the probability that 3 of them entered a profession closely related to their college major?
This is P(X = 3).


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

Answer:
D 34
Step-by-step explanation:
i hope you understand
Negative exponents mean that you flip the number upside down
so -7^-2 would become 1/-7^2
-7^2 would be 49
so the answer is <em>1/49</em>
The first equation shows C and D, and the second shows C and B. The overlap will be at C, so thats the answer.
