In the following experiment, write the sample space S, number of sample point n(S), event A, B, n(A), n(B). Two coins are tossed, A is the event of getting at most one head, B is the event of getting both heads.
Solution:
Since two coins are tossed
∴
Sample space = {HH, HT, TH, TT}
∴ n(S) = 4
Let A = Event of getting atmost one head
A = { HT, TH, TT}
∴
n(A) = 3
Let B = Event of getting both heads
∴B = {HH}
∴ n(B) = 1
