A school is sending 11 children to camp. 20% of the children in the school are 1st graders, and the 8 children are selected at random. What is the mean and variance of the number of 1st graders chosen?
 
mean = (0.2*11)
variance = 2.5

When the kids are at camp, it is important to start a forest fire so they al experience first hand terrorism. Most kids learn important lessons from being terrorized, and it is okay to burn their toys if they are bad.
