Question

PLEASE HELP ME ANSWER The probability that Scott will be late for work is 0.15. In a year Scott works for 240 days. Work out the expected number of days that he will be late......

Answer 1

36 days

Explanation:

Given

`p = 0.15` -- probability of coming late to work

`n = 240` -- number of days

Required

Determine the expected number of days of coming late (E(x))

This is calculated using:

`E(x) = np`

`E(x) = 240 * 0.15`

`E(x) = 36`

The expected number of days is 36
