Question

a wallet containing 5 five-dollar bills, 7 ten-dollar bills, and 8 twenty-dollar bills Is found and returned to its owner. the wallets owner will reward the finder with 1 bill drawn randomly from the wallet. what is the probability that the bill drawn will be a twenty-dollar bill?

Answer 1

The formula for probability is
`(number of ideal outcomes)/(number of possible outcomes)`. Because there are 8 $20 bills, there are 8 ideal outcomes and 20 possible outcomes. THis gives us
`(8)/(20)` which can be simplified to
`(2)/(5)`.

The answer is 2/5 or 0.4 or 40%.

Answer 2

2/5

Step-by-step explanation:

There are 5+7+8 = 20 total bills.

Out of these, 8 are twenty-dollar bills.

The probability of choosing 1 twenty-dollar bill is then 8/20, which simplifies to 2/5.
