Step-by-step explanation:
Given that,
No. of heads = 40
No. of tails = 60
We know that,
Probability = (no. of favourable outcomes)/(total no. of outcomes)
Experimental probability of getting heads,
no. of favourable outcomes = 40
Total no. of outcomes = 40+60 = 100
So,
She has taken 60 on denominator. She should have taken 100 instead of 60.
