Question

Harpreet tosses two different coins simultaneously (say, one is of Re 1 and other of Rs. 2). What is the probability that she gets at least one head?

Answer 1

Outcomes = (H, H), (H,T), (T, H), (T, T)

Atleast one head means that there is one and more than one heads. And from outcomes we can see that it happens 3 times.

Total number of outcomes = 4

P(probability that she gets at least one head) = 3/4
