In a pool of balls, 30% are red balls and 70% are blue balls. You are asked to pick 10 balls. What is the probability of getting 3 red balls and 7 blue balls? What is the probability of getting 5 red balls and 5 blue balls? What is the probability of getting more than 3 red balls.

Thanks!

Thanks!
