Question

a group of students enter a baseball game. 14 students buy a hotdog, 10 students buy nachos, 12 students buy popcorn, and 4 students buy pizza. find the probability that a student did not buy pizza. p(not pizza) = ?

Explanation:

Step1: Calculate total number of students

$14 + 10+12 + 4=40$

Step2: Calculate number of students who did not buy pizza

$40 - 4=36$

Step3: Calculate the probability

$P(\text{Not Pizza})=\frac{36}{40}=0.90$

Answer:

$0.90$
