Answer 1

a)

Probability that a student never visited the store

= no.of times student never visited the store/total

= 53/213 = 24.9%

b) probability that the student visited the store occasionally and found the store inconviented located

Probability = 50/213

Probability = 23.5%

c) probability that the student visited the store often given that the student felt the store inconviented located

P = 34/133

Probability = 25.6%
