There are 6 white, 5 red, and 8 blue marbles in a bag. I'm going to pick 3 marbles out of the bag.
What is the probability of:
P(exactly 2 blue and 1 red)
P(at least 2 blue)
P(3 white)
P(all different)
Out of 4 games, Team A has won 1 games in the championship series. Team B has won 3 games in the championship series. What is the experimental probability of Team A winning their next game? What is the probability of Team B winning their next game? b. Is the experimental probability a good predictor of who will win the championship?

P(taking math or science or both)
P(not taking math)
P(taking math but not science)
P(taking neither math nor science)
