The following is a known probability model for bills collected at a bank.
x | $1 | $2 | $5 | $10 | $20 | $50 | $100
P(x) | 0.35 | 0.01 | 0.25 | 0.2 | 0.1 | 0.05 | 0.04
-What is the probability that the first bill of the day that is collected is a $20 bill, the second bill collected is a $1 bill, and the third bill is a $10 bill?
-What is the probability that the first bill is not a $2 bill, the second bill is not a $2 bill and the third is not a $2 bill?
Homework Answers
| X | P(X) |
| 1 | 0.35 |
| 2 | 0.01 |
| 5 | 0.25 |
| 10 | 0.2 |
| 20 | 0.1 |
| 50 | 0.05 |
| 100 | 0.040 |
probability that the first bill of the day that is collected is
a $20 bill, the second bill collected is a $1 bill, and the third
bill is a $10 bill = 0.1*0.35*0.2=0.007
---------------
probability that the first bill is not a $2 bill, the second
bill is not a $2 bill and the third is not a $2 bill =
0.99*0.99*0.99 = 0.970299
