We know that:

When three fair coins are tossed simultaneously,

The numbers of possible outcomes are n(s) = 2= 8

The number of favorable outcomes are

n(E) = {HTT, THT, TTH} = 3

Formula: Probability of occurrence of an event $(P\left( E \right) = {{Number\ of\ favorable\ outcomes} \over {Numeber\ of\ possible\ outcomes}} = {{n\left( E \right)} \over {n\left( S \right)}})$

∴Required probability = 3/8
