In one math class of college there aer 10 males and 20 females. The professor makes 3 student teams to work on a group project.
A) How many possible teams can be made?

C) What is a probability of 3 females only?
D) What is a probabilty at least 2 females in a group?
A) Select 3 students from 10+20=30 students. The number of possible choices is C(30,3)=4060
This looks at counting and probability for teams in a college math class.
