(A) 1/2
(B) 1/4
(C) 3/4
(D) 4/3
Correct Option is: B
Probability of getting a head in one toss = 1/2
The coin is tossed twice. So 1/2 * 1/2 = 1/4 is the answer.
Here’s the verification of the above answer with the help of sample space.
When a coin is tossed twice, the sample space is {(H,H), (H,T), (T,H), (T,T)}.
Our desired event is (H,H) whose occurrence is only once out of four possible outcomes and hence, our
answer is 1/4.
