Aspinner game has a wheel with the numbers zero through 19 marked in equally spaced slots. consider a $1 bet on a number from 1 to 19. if your number hits, you have $19 returned to you; otherwise, you lose your $1 bet. find the expected return for this bet. (round your answer to two decimal places.)

The expected return for this bet is $0.05

Step-by-step explanation:

Given that A spinner game has a wheel with the numbers zero through 19 marked in equally spaced slots.

Substituting the values

Probability (winning) =

Winning amount = $19

Expected return for this bet = Winning amount x Probability(winning) - Cost of bet

=>

=>

=>0.95-1

=> 0.05
