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
