In a political science class of 50 students, 20 favor abolishing the electoral college (A) and thus electing the president of the United states by popular vote. If 2 students are selected at random from this class, what is the probability that both of them favor abolition of the electoral college? Draw a tree diagram.

The probability that both the students selected favor abolishing the electoral college is 0.16.

Step-by-step explanation:

Let X = number of students who favor abolishing the electoral college.

Of the 50 students 20 favor abolishing the electoral college.

The probability of X is, .

The random variable X follows a Binomial distribution with parameters n = 2 and p = 0.40.

The probability function of Binomial distribution is:

Compute the probability that both the students selected favor abolishing the electoral college as follows:

Thus, the probability that both the students selected favor abolishing the electoral college is 0.16.

the correct is answer is a 9-sided polygon!

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
