Solution: If

H

represents a Head and

T

represents Tail, then,Hanif will win if outcomes are

(H, H, H)

(T, T, T)

.
So,

E_{w} = 2

Total number of possible outcomes,

n (S) = 3^{2} = 9

So,Probability Hanif will win ,

P (E_{w}) = \frac{E _{w}}{n ( S )} = \frac{2}{9}

Probability Hanif will lose

= 1 - P (E_{w}) = 1 - \frac{2}{9} = \frac{7}{9}
