RW: Jelly Bean

You are given a bag of 10 jellybeans.  Answer the questions below and explain your conclusions.

1) Draw a jellybean from the bag and record the color.  Put the jellybean back in the bag and repeat this process 10 times.   If you never record that you drew a green jellybean, can you conclude that your bag of jellybeans has no green jellybeans?

2) Suppose that you did this 50 times and you still did not record a green jellybean, can you then conclude that there are no green jellybeans in your bag?

3) How many times do you need to repeat this process of drawing and replacing jellybeans to be absolutely certain that there are no green jellybeans in your bag?
