# Two-Part Question but only need the second part answered! Counting & Probability.?

William has two \$100 bills, three \$5 bills, four \$10 bills, and one \$20 bill in his wallet.  What is the probability of William randomly choosing a \$20 bill on the first draw from his wallet, and a \$10 bill on the second draw from his wallet (without replacement)?  State the answer as fraction reduced to lowest terms and also state whether the events are independent or dependent.

(I only need help with the answer to the second part below)

What would the probability have been if William had replaced the \$20 bill before making the second draw?  State the answer as a fraction reduced to lowest terms and also state whether the events are independent or dependent

10 total bills

Probability of a \$20 on first pull

1/10

Probability of a \$10 on second pull

4/9

Combined probability

1/10 * 4/9

4/90

Reduce

2/45 <–––––––
