Solution

The correct option is B

14


An explanation for the correct answer:

Step 1: Find the sample space and possible set of outcomes for given event.

We have been given that a coin is tossed twice.

S={HH,HT,TH,TT}n(S)=4

We need to find the probability of getting head both times.

Let event A: getting head both the times

A={HH}n(A)=1

Step 2: Find the required probability.

the probability of getting head both times would be,

P(A)=n(A)n(S)P(A)=14

Therefore, option (B) is the correct answer.
