Write sample space ‘S’ and number of sample point n(S) for each of the following experiments. Also write events A, B, C in the set form and write n(A), n(B), n(C).
From three men and two women, environment committee of two persons is to be formed.
Condition for event A : There must be at least one woman member.
Condition for event B : One man, one woman committee to be formed
Condition for event C : There should not be a woman member.
Sample Space, S = {M1M2, M1M3, M1F1, M1F2, M2M3, M2F1, M2F2, M3F1, M3F2, F1F2}
Number of sample points, n(S) = 10
There must be at least one woman member , A = {M1F1, M1F2, M2F1, M2F2, M3F1, M3F2, F1F2}
n(A) = 7
One man, one woman committee to be formed , B = {M1F1, M1F2, M2F1, M2F2, M3F1, M3F2}
n(B) = 6
There should not be a woman member , C = {M1M2, M1M3, M2M3}
n(C) = 3
