In a cricket match Gaurav faces 30 balls. He hits 8 fours, 5 sixes and remaining singles in his score of 70 runs . Find the probability that on playing next ball Gaurav will. 1) hit a sixer 2) make a single run 3) not be able to score
No. of runs = 70
No. of runs made in fours = 8 x 4 = 32 => 8 balls
No. of runs made in sixes = 5 x 6 = 30 => 5 balls
No. of runs in singles = 70 - (32 + 30) = 8 => 8 balls [since, 1 single takes 1 ball]
Thus, no. of no-score balls = 30 - (8 + 5 + 8) = 9
The probability we find is the chance of hitting a particular shot in a ball.
1) P(sixer) = No. of favourable outcomes / total outcomes = 5 / 30 = 1/6
2) P(single run) = No. of favourable outcomes / total outcomes = 8 / 30 = 4/15
3) P(no score) = No. of favourable outcomes / total outcomes = 9 / 30 = 3/10
No. of runs made in fours = 8 x 4 = 32 => 8 balls
No. of runs made in sixes = 5 x 6 = 30 => 5 balls
No. of runs in singles = 70 - (32 + 30) = 8 => 8 balls [since, 1 single takes 1 ball]
Thus, no. of no-score balls = 30 - (8 + 5 + 8) = 9
The probability we find is the chance of hitting a particular shot in a ball.
1) P(sixer) = No. of favourable outcomes / total outcomes = 5 / 30 = 1/6
2) P(single run) = No. of favourable outcomes / total outcomes = 8 / 30 = 4/15
3) P(no score) = No. of favourable outcomes / total outcomes = 9 / 30 = 3/10
