Answer:
The probability is 2/5 that a $20 bill will be drawn from the wallet.
Step-by-step explanation:
There are 20 total bills in the wallet (5 $5, 7 $10, and 8 $20, 5+7+8=20). So if the finder and returner of the wallet was to be given one of the bills drawn from the wallet there would be an 8/20 chance the owner of the wallet would pull a 20. That's because there are 20 total bills in the wallet and 8 of them are $20.
Simplifying 8/20... 8/20= 4/10= 2/5.
So, there is a 2/5 chance that a $20 bill will be pulled out of the wallet.
Hope this helps!
