roulette expected value,We use the above information with the formula for expected value. Since we have a discrete random variable X for net winnings, the expected value of betting $1 on red in roulette is: P(Red) x (Value of X for Red) + P(Not Red) x (Value of X for Not Red) = 18/38 x 1 + 20/38 x (-1) = -0.053.

The expected value formula is this: E (x) = x1 * P (x1) + x2 * P (x2) + x3 * P (x3).. x is the outcome of the event. P (x) is the probability of the event occurring. You can have as many x z * P(x z) s in the . Definition: expected value. Let X be a numerically-valued discrete random variable with sample space Ω and distribution function m(x). The expected value E(X) is defined by. E(X) = ∑ x ∈ Ωxm(x) , provided this sum converges absolutely. We often refer to the expected value as the mean and denote E(X) by μ for short.
