In a cricket match, a batsman hits a boundary 6 times out of 30 balls he plays. Find the probability that on a ball played: he hits boundary    (ii)  he does not hit a boundary.

Explanation

Total number of balls played=`30`
(i)Number of times batswoman hit a boundary=`6`
`therefore P("the batsman hits boundary")=6/30=0.2`
(ii)Number of times batswoman did not hit a boundary=`30−6=24`
`therefore P("the batsman does not hit boundary")=24/30=0.8`
