QuestionA jar has 63 marbles: 8 red, 25 blue, 30 green. Draw a marble: win \$20 (red), lose \$10 (blue), lose \$5 (green). Find the expected outcome.

Studdy Solution
Calculate the total expected value.
$$(total) = \$20 \\times \frac{8}{63} - \$10 \\times \frac{25}{63} - \$5 \\times \frac{30}{63} = -\$0.79$$The expected outcome of this game is a loss of $0.79.
