Your expected win from this bet would be about -0.05, meaning that you can expect to lose 5 cents on each $1 bet.
To find this we multiply the probability for each bet times $1. Remember in Roulette, there are 18 red, 18 black and 2 zero spaces.
(18/38) x 1 + (20/38) x -1 = -0.05

Answer:
Expected value for this bet if you bet $1 is 0.97$.
Step-by-step explanation:
There are 37 numbers (including 0) on the roulette wheel. To find the expected value of betting 1$ to odd or even number, we need to multiply the number of event with what you will earn and divide it the total number of event.
[tex]E(x)=(18*2+18*0+1*0)/37=36/37=0.97[/tex]
Expected value for this bet is 0.97$
