Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is
.
Step-by-step explanation:
From the given question, the bag contains;
$1 bill = 7
$5 bill = 1
$10 bill = 3
$20 bill = 2
Total number of bills in the bag = 13
Pulling a bill at random, the bills would have an expected value as follows:
For $1 bill, the expected value =![\frac{7}{13}](/tpl/images/0999/7818/f86e0.png)
For $5 bill, expected value =![\frac{1}{13}](/tpl/images/0999/7818/6d05b.png)
For $10 bill, expected value =![\frac{3}{13}](/tpl/images/0999/7818/a0fe4.png)
For $20 bill, the expected value =![\frac{2}{13}](/tpl/images/0999/7818/a1424.png)
Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is
