Expected values for binomial random variables i.

### Formula expected value - der

Expected values for binomial random variables i. Petersburg Paradox What is Expected Value? We will call this advantage mathematical hope. The math behind this kind of expected value is: It follows directly from the discrete case definition that if X is a constant random variable , i. The formula will give different estimates using different samples of data, so the estimate it gives is itself a random variable. Therefore, the absolute value of expectation of a random variable is less than or equal to the expectation of its absolute value:.### Formula expected value Video
