Abox contains eighteen $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill. you blindly reach into the box and draw a bill at random what is the expected value of your draw? the expected value of the draw is $ (round to the nearest cent.)

 $7.70

Step-by-step explanation:

Given : A box contains eighteen $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill.

Total bills =

We know that probability of any event =

i.e. the probability of getting $1 bills =

Probability of getting $10 bills =

Probability of getting $5 bills =

Probability of getting $20 bills =

Probability of getting $100 bills =

Hence, the expected value of your draw= $7.70

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
