From a group of 2 men (M1, M2) and three women (W1, W2, W3), two persons are selected. Describe the sample space of the experiment. If E is the event in which one man and one woman are selected, then which are the cases favourable to E?
उत्तर
Let S be the sample space of given event.
∴ S = { (M1, M2), (M1, W1), (M1, W2), (M1, W3), (M2, W1), (M2, W2), (M2, W3), (W1, W2) (W1, W3), (W2, W3)}
Let E be the event that one man and one woman are selected.
∴ E = {(M1, W1), (M1, W2), (M1, W3), (M2, W1), (M2, W2), (M2, W3)}
