Of the Statistics graduates of a University 40%, received a starting salary of

$45,000.00. If 6 of them are randomly selected, find the probability that all the graduated had

starting salary of $45,000.00.

Solution

this is binomial distribution problem

n = 6

p = 0.4

probability that all graduated had starting salary of 45000000

= P(X =6)

= 6C6 * 0.4^6 * 0.6^0

= 0.004096
