If k is a constant function then expectation of k is |
|
Answer» Answer: The EXPECTED VALUE of a CONSTANT is just the constant, so for example E(1) = 1. MULTIPLYING a random VARIABLE by a constant multiplies the expected value by that constant, so E[2X] = 2E[X]. A useful formula, where a and b are constants, is: E[aX + b] = aE[X] + b |
