Challenge #1

Design a spinner that has a 2/3 probability of landing on the number 3. Precisely draw this spinner.

Challenge #2

Andre picks a block out of a bag 60 times and notes that 43 of them were green.

(1.) What should Andre estimate for the probability of picking out a green block from this bag?

(2.) Mai looks in the bag and sees that there are 6 blocks in the bag. Should Andre change his estimate based on this information? If so, what should the new estimate be? If not, explain your reasoning.
