Formula used:

Probability of occurrence of the event:

P(E) =  \(\frac{n(E)}{n(S)}\)

Where,

n(E) = Number of favorable outcome

n(S) = Number of possible outcome

Calculation:

A batsman hits sixes 8 times out of 60 balls then

Probability of getting sixes

P(A) = \(\rm \frac{8}{60}\) = \(\rm \frac{2}{15}\)

The probability that he does not hit a six

P(A̅) = 1 − \(\rm \frac{2}{15}\) 

P(A̅) \(\rm \frac{13}{15}\)

∴ Required probability is \(\rm \frac{13}{15}\).
