Do you remember probabiliby

Mrs. Simpson has a great problem at her site.

I would like you to answer it here and copy and paste your answer into her blog here.

In the Gee Whiz Everyone Wins! television game show, members of the studio audience draw a block randomly from a bucket containing 2 red blocks, 1 yellow block, and 3 blue blocks. If a blue block is drawn, the contestant wins $5. If a red block is drawn, the contestant wins $10. If the yellow block is drawn, the contestant wins $50. The block is replaced after each draw.

a. What is the probability of drawing each color?

b. If 24 contestants draw a block from the bucket, how much money can the game show expect to pay out?

Remember Answer the question here and at the Alabama Blog Site.
