Answer:
Step-by-step explanation:
Given that the total number of accident recorded per year is 5
this can be taken as the sample size= 5
the sample size is then given as 3
we know that the probability of an even happening is
P(E)= number of event/number of possible outcome
therefore the probability of exactly 3 accident happening is given as
Pr(3 accident)= 3/5
=3/5
