In a cricket match, a batswoman hits a boundary 6 times out of 30 balls she plays. Find the probability that she did not hit a boundary.

Solution

Number of times the batswoman hits a boundary = 6

Total number of balls played = 30

∴ Number of times that the batswoman does not hit a boundary = 30 − 6 = 24

`"P (She does not hit a boundary) "="Number of times when she does not hit boundary"/"Total number of balls played" = 24/30 = 4/5`
