# 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:**

The probability of an event is given as,

P(E) = Number of instances of the event taking place / Total number of instances

Number of balls played = 30

Number of balls for which the batswoman hits boundary = 6

Thus, number of balls for which the batswoman does not hit a boundary = 30 – 6 = 24

Probability of the batswoman not hitting a boundary = Number of balls for which the batswoman does not hit the boundary / Total number of balls played

= 24 / 30 = 4 / 5
