Hello...
Answer :- 1/4
EXPLANATION :- Let E1 = event of getting 2 heads.
E1 = {HH} and, therefore, n(E1) = 1.
P(getting 2 heads) = P(E1) = n(E1)/n(S) = 1/4.
Answer :- 1/4

When two coins are tossed, The possible events are ( Tails - Tails, Tails - Heads, Heads - Heads, Heads - Tails.)
So , There are 4 possible events.
Probability of getting two heads P(H,H) = Favourable events / Total events = 1 / 4 .
Hence, The required option is 1/4
