Question

A jar is filled with 59 different colored marbles, 10 of which are red, 31 of which are blue, and 18 of which are green. A player is asked to draw a single marble from the jar and if they draw a red marble they will win $20, if they draw a blue marble they will lose $10, and if they draw a green marble they will lose $5. You may round your answer to the nearest cent.

Answer 1

Explanation:

I guess you want to find the expected amount you win or lose

Expectation = 20(10/59) - 10(31/59) - 5(18/59)

= 200/59 - 310/59 - 90/59

= -200/59

= $ -3.39
