Solution

All possible outcomes are HH, HT, TH and TT.

‚ÄčTotal number of outcomes = 4.

Getting 2 heads means getting HH.

Numbers of favourable outcomes = 1.

∴ P(getting 2 heads) = `("Number of favourable outcomes")/"Number of all possible outcomes"`

`= 1/4`

Thus, the probability of getting 2 heads is `1/4`.

Hence, the correct answer is option (d).
