Question

A survey of 1500 people about their favorite fast food restuarant. Here are the results. 40% said they like Zaxby's 90% said they like Chick-Fil-A Using the area model above, what is the probability of choosing a person at random who does NOT like Zaxby's?

Answer 1

Answer: The probability of choosing a person at random who does NOT like Zaxby's = 0.6

Explanation:

Given : The result of survey of 1500 people about their favorite fast food restaurant.: 40% → like Zaxby's , 90% → like Chick-Fil-A

Now, the probability of choosing a person at random who does NOT like Zaxby's = percent of people does not like Zaxby's

= 100% - ( percent of people like Zaxby's)

= 100% - 40%

= 60% or 0.6 [
`60%=(60)/(100)=0.6`]

Hence, the probability of choosing a person at random who does NOT like Zaxby's = 0.6
