A coin has two sides head (H) and tail(T).
If we toss three coins then the possible outcomes are as follows:

(H,H,H) (H,H,T),(H,T,H),(T,H,H),(H,T,T),(T,H,T),(T,T,H) & (T,T,T)

SOLUTION:

Number of possible outcomes=8
{(H,H,H) (H,H,T),(H,T,H),(T,H,H),(H,T,T),(T,H,T),(T,T,H) & (T,T,T)}
Hence probability = 3/8
