Question

Two coins are tossed simultaneously. Find the probability of getting (i) exactly 1 head (ii) at most 1 head (iii) at least 1 head Select the correct answer from above options

Answer 1

Two coins are tossed: Sample space = {HH, HT, TH, TT} Total number of outcomes = 4 P(getting a tail) = 1/2. Now, (i) P(exactly 1 head) = 2/4 = 1/2 (ii) P(at most 1 head) = 3/4 (iii) P(at least 1 head) = 3/4
