Answer 1

`P(x < 4) = (9)/(50)`

Explanation:

Given

`n(S) = 50`

See attachment for distribution

Required

`P(x < 4)`

This is calculated as:

`P(x < 4) = (n(1) + n(2) + n(3))/(n(S))`

Using the data on the frequency distribution table, we have:

`P(x < 4) = (4 + 2 + 3)/(50)`

`P(x < 4) = (9)/(50)`
