Calculating probability, expectation and standard deviation
Consider a random variable with the following probability distribution: P(X = 0) = 0.1, P(X = 1) = 0.2, P(X = 2) = 0.3, P(X = 3) = 0.3, and P(X = 4) = 0.1, A) Find : P(X > 3 3|X > 2) B) Find the expected value of X C) Find the standard deviation of X
