Question

if two coin are tossed, find the probability of event, at least one head appeared in event​

Answer 1

Answer:

getting at least 1 head:

Let E6 = event of getting at least 1 head. Then, E6 = {HT, TH, HH} and, therefore, n(E6) = 3. Therefore, P(getting at least 1 head) = P(E6) = n(E6)/n(S) = ¾.
