Answer:

Answer:

The required probability is 1 .

Step-by-step explanation:

In any event , the sum of P(A) and P'(A) is always 1 .

Here , in a cricket match , the batswoman hits a boundary 25 times out of the 60 balls she plays .

The total number of balls ( Sample Space ) 60

Favourable Cases ( The no of times she hit a boundary ) > 25

Unfavourable Cases > 35

Probability that she hit a boundary > 25/60

Probability that she didn't hit a boundary > 35/60

Probability that she hit a boundary + Probability that she didn't hit a boundary

> 25/60 + 35/60

> 60/60

> 1
