In a cricket match a batsman hits a boundary 12 times out of 80 balls he plays further if he plays one ball more what will be the probability that:(i) he hits a boundary(ii) he does not hit a boundary
(i) Total number of balls = 80
Hits boundaries = 12 times
∴ P (Hitting a boundary) = 12/80 = 3/20
(ii) P (of not hitting a boundary) = 68/80 = 17/20
