Question

Can someone help me please?

Answer 1

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,

`P=(40)/(100)`

She has taken 60 on denominator. She should have taken 100 instead of 60.
