You have three $1 bills, four $5 bills, and two $10 bills in your wallet. You select a bill at random. Without replacing the bil
castortr0y [4]
<h2>Greetings!</h2><h3>To find the first probability, you first find the amount of $10 bills and the total amount. Then you can put this into a fraction:</h3>

\frac{2}{9}

<h3>Now, do the same but for the total amount, be sure to remove 1 because you have not returned the first one picked. Now find the amount of $1 bills too:</h3>

\frac{3}{8}

<h3>Now you have two fractions of two consecutive events, now just simply multiply the two together:</h3>

\frac{2}{9} x \frac{3}{8} = \frac{6}{72}

<h3>Now as both numbers are factors of 6, both can be divided by 6 to get a simplified probability:</h3>

\frac{6}{72} ÷ 6 = \frac{1}{12}

<h3>So P($10 then $1) = \frac{1}{12}</h3>
