Question

In a cricket match, a batswoman hits a boundary 8 times out of 42 balls she plays. Find the probability that she did not hit a boundary.​

Answer 1

no hit : 42-8 = 34

p = 34/42 = 17/21

Answer 2

`(17)/(21)`

Based on the given conditions, formulate:

`\downarrow`

`(42-8)/ 42`

Calculate

`(42-8)/(42)`

Calculate the sum or difference

`(34)/(42)`

Cross out the common factor

`(17)/(21)`
