Question

Analysis of visitor behavior has shown that fans are equally likely to leave the stadium through any of the 5 marked stadium exits. What is the probability of a visitor exiting through either exit A or exit B?

0.20

0.40

0.02

0.04

Answer 1

0.40

Explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Exit A or exit B, so 2 desired outcomes.

This means that
`D = 2`

Total outcomes:

Any of the 5 exits, so
`T = 5`

Probability:

`p = (2)/(5) = 0.4`
