प्रश्न

In a cricket match, a batsman hits a boundary 12 times out of 80 balls he plays, further, if he plays one ball more, what will be the probability that:
(i) he hits a boundary
(ii) he does not hit a boundary

बेरीज

उत्तर

(i) Total number of balls = 80

Hits boundaries = 12 times

∴ P (Hitting a boundary) = `12/80=3/20`

(ii) P (of not hitting a boundary) = `68/80=17/20`
