In a cricket match, a batsman hit a boundary 6 times (out of 30 balls). Find the probability that next ball he plays is not a boundary.
The correct option is
Total number of balls played = 30
Number of balls in which the batsman hit a boundary = 6
Number of balls in which he did not hit a boundary
= 30 – 6
So, probability that next ball he play s is not a boundary is 2430=0.8
Hence, option D is correct.
