## Question

### Solution

Correct option is

When two coins are tossed, there may be 1 head, 2 heads or no head at all.

Thus, the possible values of X are 0, 1, 2,

Now,

P(X = 0) = P(getting no head) = P(TT) =

P(X = 1) = P(getting one head)

= P(HT or TH)

P(X = 2) = P(getting two heads) = P(HH) =

Thus, the required probability distribution of X is given by
