In a business class there are 6 men and 10 women. 3 students are randomly selected to present a topic. What is the probability that at least 1 of the 3 students selected is female?
Solution
There can be three cases:
1. 1 female and 2 male
2. 2 female and 1 male
3. all 3 female
So probability of at least 1 female getting selected is = (10C1 . 6C2 + 10C2 . 6C1 + 10C3) / 16C3
