# Discrete Probability Distributions

What is the probability that the sum of two dice will be less than 5? How many throws will it take you to hit your first "bullseye" on a dart board? Use discrete probability distributions to find out!

A basketball player is practicing 3-pointers. If the probability that he successfully scores each shot is \(\frac{4}{5},\) what is the expected value of the points he scores after throwing \(100\) shots?

**Note:** The player scores 3 points for each successful shot.

A basketball player is practicing 3-pointers. If the probability that he successfully scores each shot is \(\frac{3}{5},\) what is the variance of the points he scores after throwing \(800\) shots?
