However if we take p1 = p2 = p then we have: MX + Y(t) = MX(t) ⋅ My(t) = (q + pet)n1 ⋅ (q + pet)n2 = (q + pet)n1 + n2 laser vision safety glasses

WebFeb 6, 2024 · I want to create a function which places numbers within a range [0,1] into a bin where n is the number of bins and the boundaries are defined relative to the mid point. 0.0 >= Bin 1 <= 0.2 <- outer left bin 0.2 > Bin 2 <= 0.4 0.4 > Bin 3 < 0.6 <- middle bin 0.6 >= Bin 4 < 0.8 0.8 >= Bin 5 <= 1 <- outer right bin WebIt comes from the definition of expected value of a random variable Y: E [Y] = 0*p (Y=0) + 1*p (Y=1) + .. + n*p (Y=n). As defined by Sal in this example, the random variabla Y only takes the values Y=0 and Y=1. Moreover, we have that p (Y=1) = p and p (Y=0) = 1-p. This leads to E [Y] = p.
