When two coins are tossed, what is the probability that two heads are obtained?

Text Solution

Verified by Experts

Sample space when two coins are tossed (S) = {H H. T T, H T, F H}
n(S) = 4
Event of getting two heads (A) = {H H}
n(A) = 1
Probability of getting two heads `P(A) = (n(A))/(n(S)) = (1)/(4)`
