Question

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

Answer 1

Total number of possible outcomes, n(S) = 4 

Number of favorable outcomes, 

n(E) = 3

∴ P(E) = \(\frac{n(E)}{n(S)}\) = \(\frac{3}{4}\)
