If you know how to compute E [ X] and V a r ( X) for a dice roll, then you can work out E [ X 2] using this equivalence of variance: V a r ( X) = E [ X 2] − ( E [ X]) 2. While this is not a general answer (see @Glen_b), this equivalence comes in handy pretty often. Share.

Visit Stack Exchange Web1 aug. 2024 · Expectation E (XY) of two dependent variables. In your example of coin tosses, you actually have Y = n − X. So E [ X Y] = E [ X ( n − X)] = n E [ X] − E [ X 2]. Since X ∼ B i n o m i a l ( n, p), where p is the probability of heads on a single coin toss, you can calculate this by using the formula for E [ X] and E [ X 2] when X has such ...
Web25 jan. 2024 · for (i=1; i<=n, i++) e= 1+1/factorial (i); This is wrong, you are not adding to e, you are assigning always the last value of the series, which is always 0 (except for i = 1 ). So your e will always be 1. factorial is a function that returns an int. A int divided by an int is an int and in C anything 1/x (for x > 1, x integer) is 0. Webe/m = 2V/B2r2 from which students could calculate values of e/m; or r2 = 2Vm/eB2 from which students could plot a graph of r2 against V and find e/m from the gradient. Using values for speed: A simple rearrangement of equation 2 gives, r = mv/Be; So a graph of r (radius) against v (speed) will yield a value for e/m.

Web1. jbowman has already mentioned the law of total variance, but I think the matter can be stated more simply than in that answer. var ( S) = var ( E ( S ∣ D)) + E ( var ( S ∣ D)). I.e. the total variance of S is the variance of the conditional expected value plus the expected value of the conditional variance.
