Question

2) Suppose 120 people are surveyed and asked about their eating habits. 50 people

stated that they like Raising Cane's chicken fingers, 80 people said that they like

Layne's chicken fingers. If 10 people don't like either, then...

a) What is the probability that someone surveyed likes both Raising Cane's and

Layne's chicken fingers?

Answer 1

1/6

Explanation:

Given that :

Total surveyed (u) = 120

n(Cane's chicken fingers) = 50

n(Layne's chicken fingers) = 80

n(do not like either) = 10

a)

What is the probability that someone surveyed likes both Raising Cane's and Layne's chicken fingers?

n(Cane's n Layne's) = 20

u = 120

P = required outcome / total possible outcomes

P(Layne's and Cane's chicken) = [n(Cane's n Layne's)/ u]

= 20 / 120

= 1/6
