WebJul 29, 2012 · You are simply saying Pr ( d, c) = Pr ( d ∣ c) Pr ( c) where d = a ∩ b. Combine this with Pr ( a, b, c) = Pr ( a ∣ b, c) Pr ( b, c) = Pr ( a ∣ b, c) Pr ( b ∣ c) Pr ( c) and divide through by nonzero Pr ( c) to get Pr ( a, b ∣ c) = Pr ( a ∣ b, c) Pr ( b ∣ c).

For example, to find pX Y (x 1), we divide each entry in the Y=1 row by pY (1)=1/2. Read More: What type of splint is used for ...
WebAs the conditional distribution of X given Y suggests, there are three sub-populations here, namely the Y = 0 sub-population, the Y = 1 sub-population and the Y = 2 sub-population. Therefore, we have three conditional means to calculate, one for each sub-population.
