B Yes it is unusual. The probability of there being more than two motor vehicle deaths on the same day is very small

C, No it is not unusual. The probability of there being more than two motor vehicle deaths on the same day is greater than 0

D No it is not unusual. The probability of there being more than two motor vehicle deaths on the same day is very small.

mean number of deaths per day = 34.6 / 365 = 0.095

probability = 0.0005
