Solution

When three coins are tossed together, the possible outcomes are

HHH, HTH, HHT, THH, THT, TTH, HTT, TTT

∴ Total number of possible outcomes = 8

Favourable outcomes of at least two heads are HHH, HTH, HHT, THH

∴ Total number of favourable outcomes = 4

∴ P(at least two heads) =`4/8=1/2`
