if 4 women and 6 men work in the accounting department in how many ways can a committee of 3 be formed if it has to include at least one woman?
36
60
72
80
100
i can find solution by reverse method (total combination - committee entirely men ) but can't get right answer by direct method (one woman 2 men, 2 woman 1 men etc.)
