If 3 coins tossed then
sample space = {(H,H,H);(H,H,T);(H,T,H);(H,T,T);(T,T,T);(T,T,H);(T,H,T);(T,H,H)}
No of possible outcomes of getting 2heads= 4
Probability = (no of possible outcomes )/(total no of outcomes )
P(E) = 4/8
P(E) = 1/2
sample space = {(H,H,H);(H,H,T);(H,T,H);(H,T,T);(T,T,T);(T,T,H);(T,H,T);(T,H,H)}
