Q89. From a group of 10 men and 5 women, four member committees are to be formed each of which must contain at least one women. Then the probability for these committees to have more women than men, is : (1) 3 (2) 2 11 23 (3) 1 (4) 21 11 220
What This Question Tests
This question involves counting combinations for specific conditions (at least one woman, more women than men) to calculate the probability, requiring careful case analysis and calculation.
