Question

John runs a computer software store. He counted 128 people who walked by his store in a day, 60 of whom came into the store. Of the 60, only 21 bought something in the store. Estimate the probability that a person who walks by the store will enter the store. Round your answer to the nearest hundredth. g

Answer 1

The probability is 0.47.

Explanation:

Given,

Total number of people who walked by his store = 128,

Out of these people the number of people who came into the store = 60,

Hence, the probability that a person who walks by the store will enter the store

`=\frac{\text{People who came in store}}{\text{People who walked by store}}`

`=(60)/(128)`

`=0.46875`

`\approx 0.47`
