Answer:
chance to grab both $20 bills
Step-by-step explanation:
There are ten bills in total.
The probability that the first dollar she picks is a twenty-dollar bill is 2/10 because she can pick either of the two twenty-dollar bills out of the ten in her wallet. Next, we need to pick the second bill. There are nine bills left, and only one is a twenty-dollar bill. The probability of choosing a second dollar bill is 1/9.
(2/10)*(1/9)=2/90=1/45
