Two coinsare tossed simultaneously. What is the probability of getting at least onehead?

Answer» 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`.
