# 1/2.#

The Sample Space #S# associated with the Random Experiment in

Question is given by,

#S={(H,H), (H,T),(T,H), (T,T)}.#

#:. n(S)=4.#

Suppose that,

The Event A =getting #2# Heads,

The Event B =getting #2# Tails, and,

The Event C =getting a Head and a Tail.

Then, we have,

#A={(H,H)}, B={(T,T)}, &, C={(H,T),(T,H)}.#

#:. n(A)=n(B)=1, and, n(C)=2.#

#rArr P(A)=(n(A))/(n(S))=1/4.#

Similarly, #P(B)=1/4, and, P(C)=2/4=1/2.#
