1. simulation to represent the following situations:
   1. At a horse track, Victory the Horse, has a 40% chance of winning the next 4 races. What is the probability of Victory the Horse winning at least one race?
   2. In a box of 100 chocolate bars, there are 20 Kit Kats, 30 Smarties, 10 Coffee Crisps, and 40 Aeros. You draw a chocolate bar and replace it. What is the probability of drawing at least 3 Smarties?
2. Design a simulation that will give you a guess as to how many people have the same birthday in a group of 100. The number of days in a year is 365.
3. A coin has been tossed 100 times. Of the 100 times, a head appears 80 times. Why would someone assume that the coin is unfair?
