What is the likelihood that a GREEN block is pulled from the pile?
Likely
300
Three RED blocks and Seven GREEN blocks are in a pile together.
If you pull 20 blocks from the pile and put each block back after each pull, how many times would you predict a RED block is pulled?
3/10times20=6

DOUBLE JEOPARDY
You have a spinner with 5 equal sized sections. One section is red, two sections are brown, and 2 sections are green.
Create a probability model for the spinner.
S=( R, B, B, G, G)
P(Red) = 1/5
P(Brown) = 2/5
P(Green) = 2/5
