AP Statistics: Probability Activity with Poker Chips
Answer each question using the poker chips (Set A) provided. Record the number on the bag.
Using initials Y B G for colors, find the following probabilities:
1. P(B) = 6/30
2. P(1) = 10/30
For each of these, find the probability and make a Venn diagram to illustrate. Confirm your
probability using the general probability formulas.
3. P(Y C ) = 21/30
4. P(Y È G) = 24/30
5. P(Y È1C ) = 23/30
6. P ( (1È 2)C ) = 0
For each of these, find the probability and make a Venn diagram to illustrate. Are the events
independent? Verify the independence using an equation.
7. P(G Ç 2) = 10/30
8. P(1Ç 2) = 0
For each of these, find the probability and make a Venn diagram to illustrate.
9. P(GC Ç 2) = 10/30
10. P(Y Ç1) = 3/30
11. P(2C Ç G) = 5/30
Find the following conditional probabilities and confirm using the formula for conditional
probabilities.
12. P(Y | 2) = 6/20
13. P(2 | Y ) = 6/9
14. P(1 | G) = 5/15
15. P(Y | BC ) = 9/24
16. P(2C | Y ) = 3/9
