At a local community college, 56% of students who enter the college as freshmen go on to graduate. eight freshmen are randomly selected. a. what is the probability that none of them graduates from the local community college

0.0014

Step-by-step explanation:

In binomial probability distribution , The probability of getting success in x trials (where x is a binomial variable ) :

, where p= probability of getting success in each trial.

n= Total number of trials.

Given : The proportion of students who enter the college as freshmen go on to graduate : p= 0.56

Sample size : n= 8

Let x represents the students in the college who enter the college as freshmen go on to graduate.

Then, the probability that none of them graduates from the local community college will be :_

Hence, the required probability =0.0014

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
