11. advertising three out of four people think most ad-
vertising seeks to persuade people to buy things they
don't need or can't afford. find the probability that
exactly 5 out of 9 randomly selected people will agree
with this statement.

0.1168

Step-by-step explanation:

This is binomial distribution probability. The formula to solve this is:

Where

p is the probability of success [3/4 or 0.75]

q is the probability of failure [1 - 0.75 = 0.25]

n is total number [we choose 9 people, so n = 9]

x is what we are trying to find [here we want 5 people agreeing, so x = 5]

Putting the information into the formula, we calculate the probability:

Hence, the probability is 0.1168
