Question

Allyn surveyed the teachers she works with at GCA to find out how many cars they own. She created a probability distribution which is displayed below. What is the average number of cars owned by each teacher?

Answer 1

As show in the table,
0 - 0.031 - 0.132 - 0.703 - 0.104 - 0.04
Allyn surveyed the teachers she works with at GCA to find out how many cars they own. She created a probability distribution. The average number of cars owned by each teacher is
13 + 140 + 30 + 16 = 199 (the total number of cars)
Assume that there are 100 teachers,So 199 / 100 = 1.99
So, technically the average number of cars owned by each teacher is 1 or 2
