We have total 30 balls which are grouped by size and color as follows. What is the probability that a randomly chosen ball is not large or not yellow? Large Small Red 5 5 Blue 4 6 Yellow 7 3
Homework Answers
| Large | Small | |
| Red | 5 | 5 |
| Blue | 4 | 6 |
| Yellow | 7 | 3 |
P(a randomly chosen ball is not large or not yellow) = 1 - P(a randomly chosen ball is large and yellow)
= 1 - 7/30
= 23/30

Urn A contains 7 yellow balls and 3 red balls. Urn B contains 10 yellow balls and 7 red balls. Urn C contains 12 yellow balls and 4 red balls. An urn is picked randomly (assume that each urn is equally likely to be chosen), and then a ball is picked from the selected urn. What is the probability that the chosen ball came from urn B, given that it was a yellow ball?
