Eddie Dickerson · Answer 1

The expected value of your winnings is $0.8

Explanation:

Expected value is calculated by multiplying the probability with the value of each outcome and adding them all.

The value of the first outcome is 2 and the probability is 25% so the expected

The value of the second outcome is 1 and the probability is 30%.

The value of the third outcome is 0 and the probability is (100 - (25+30) = 100-55=45%

Expected value of winnings = (2*0.25) + (1*0.3) + (0*0.45)

=0.5+0.3+0

=0.8

The expected value of your winnings is $0.8
