Webb6 mars 2024 · You use a sum of the probability density functions fX1 and fX2 when the probability (of say Z) is a defined by a single sum of different probabilities. For example when Z is a fraction s of the time defined by X1 and a fraction 1 − s of the time defined by X2, then you get P(Z = z) = sP(X1 = z) + (1 − s)P(X2 = z) and fZ(z) = sfX1(z) + (1 − s)fX2(z)

In order to prove b ( x, n, p) = ( n x) p x ( 1 − p) n − x f o r x = 0, 1, 2,..., n (and 0 otherwise) we must show 1 = ∑ x = 0 n ( n x) p x ( 1 − p) n − x. However, all the answers I've seen are just stating the binomial theorem with no work shown. Would anyone be willing to show me the steps for ...

Since we have the distribution of C, it is easy to compute this probability. Doing this we find that (7.1.9) P ( C ≥ 13) = .2485, so that about one in four hands should be an opening bid according to this simplified model.
