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 no. of possible outcomes = 4 which are{HT, HH, TT, TH}

E ⟶ event of getting at least one head

No. of favourable outcomes = 3 {HT, HH, TH}

Probability, P(E) = (No.of favorable outcomes)/(Total no.of possible outcomes)

P(E) = 3/4
