Respuesta :

mathmate
Total number of members = 10+11=21
Probability of choosing first woman into committee= 11/21
Probability of choosing first woman into committee= 10/20
Probability of choosing first woman into committee= 9/19
Assume independence of choices, then
Probability of choosing an all women committee
= 11/21 * 10/20 * 9/19
= 33/266
