Question
Three coins are tossed. Describe Two events which are mutually exclusive.
✓
Answer
When three coins are tossed then sample space (S) is given by S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} Let event A: getting at least two heads = {HHH, HHT, HTH, THH} and event B: getting at least two tails = {HTT, THT, TTH, TTT} There should not be any element common for the events to be mutually exclusive. since ${A\cap B=\phi}$ Thus A and B are mutually exclusive events.
