The mean of the rainfall during four month period.

April = 35

May = 25

June = 60

July = 40

Mean =The sum of the four months rainfall ÷ 4

The sum of the four month rainfall = 35 + 25 + 60 + 40

To know the probability of people not wearing glasses = Number of people in the room – Number of people wearing glasses

= 24 – 6

= 18
