Question

Two coins are tossed simultaneously. What is the probability of getting at least one head? Select the correct answer from above options

Answer 1

When two coins are tossed simultaneously, all possible outcomes are HH, HT, TH, TT. Total number of possible outcomes = 4. Let E be the event of getting at least one head. Then, E is the event of getting 1 head or 2 heads. So, the favourable outcomes are HT, TH, HH. Number of favourable outcomes = 3. `:. ` P(getting at least one head ) ` =P(E) = 3/4`.
