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.

Number of times the batswoman hit a boundary=6(given)
Total balls she played=30
Probability (hitting a boundary)=Number of times she hit a boundary/Total number of balls she played=6/30
Probability (hitting a boundary)=1/5
Probability of not hitting a boundary=1−Probability (hitting a boundary)=1−1/5=4/5
Alternate Way
Number of times the batswoman does not hit a boundary=Total balls she played - Number of times the batswoman hit a boundary=30−6=24
Probability of not hitting a boundary=Number of times she does not hit a boundary/Total number of balls she played=24/30=4/5
