five people are randomly selected from a group of 67 women and 33 men. find the probability that the selection consists of an odd number of women

This must be done case-wise. Consider each possibility that has an odd number of women and add their probabilities.

Dr. Trushit Patel

Five people are selected.

So women can be selected either, 1, 3 or 5

Probability (selection consists of an odd number of women) = [1C67 * 4C33]/5C100 + [3C67 * 2C33]/5C100 + [5C67 * 0C33]/5C100

Calculate it using a calculator.
