question 13

Short Answer

Urn 1 contains 2 blue tokens and 8 red tokens; urn 2 contains 12 blue tokens and 3 red tokens. You roll a die
to determine which urn to choose: if you roll a 1 or 2 you choose urn 1; if you roll a 3, 4, 5, or 6 you choose
urn 2. Once the urn is chosen, you draw out a token at random from that urn. Given that the token is blue,
what is the probability that the token came from urn 1?
In questions 45-47 a bowl has eight ping pong balls numbered 1,2,2,3,4,5,5,5. You pick a ball at random.
