Total number of balls played by a player = 30
Number of times he hits a boundary = 6
Number of times he does not hit a boundary
= 30 – 6
= 24
We know,
Probability of an event = (Number of Favorable outcomes) / (Total Numbers of outcomes)
Now,
(i) Probability (he hits boundary) = (Number of times he hit a boundary) / (Total number of balls he played)
= \(\frac{6}{30}\)
= \(\frac{1}{5}\)
(ii) Probability that the batsman does not hit a boundary
= \(\frac{24}{30}\)
= \(\frac{4}{5}\)
