Question

3 coins are tossed in the air at the same time probability of 2 tails

Answer 1

The sample space (set of all possible outcomes) when we toss three coins is

{HHH, HHT, HTH, THH, TTH, THT, HTT, TTT}.

We see that {TTH, THT, HTT, TTT} have at least two tails. Therefore 4 out of 8 outcomes have at least two tails

P(at least 2 tails) = 4/8 = 1/2.   Ans
