Question

When two coins are tossed together, what is the probability of getting at least one tail?

Answer 1

When two coins are tossed together, there are four equally likely outcomes, i.e., S ={ HH, HT, TH, TT } The outcomes having at least one tail are HT, TH and TT, i.e., 3.

\(\therefore\) P (at least one tail) = \(\frac{3}{4}\).
