<PRE><B>Question 390478</B>
 There are 2 girls and 7 boys in a math club. A team of four persons must be chosen for a tournament, and there must be at least 1 girl on the team. In how many ways can this be done?
-----
P(at least one girl on the team) = 1 - P(no girls on the team)
---
= 1 - 7C4/9C4
= 1 - 0.278
= 0.722
