Question

In a shooting competition, the probability of a man hitting a target is 2/5.If he fires 5 times, what is the probability of hitting the target (1) at least twice (2) at most twice.

Answer 1

n(S)=5
let event of firing target be A
n(A)=5
probability of (A)=n(A)/n(S)
2/5=5/5
2/5=1
therefore,probability will be 0.4%
