- A sample is selected from one of two populations, S, and S₂, with P(S₁) = 0.6 and P(S₂) = 0.4. The probabilities that an event A occurs, given that event S, or S₂ has occurred are P(A|S₂) = = 0.4 and P(AIS₂) = 0.3 and the probability of event A is P(A) = 0.36. Use Bayes' Rule to find P(S, IA).

On any given vote, members vote independently. Whereas Republicans always vote their party line, Democrats vote their party line with probability .8, and vote Republican with probability .2. On a rainy day only 3 committee members (selected w/o replacement) were present. Let X = number of Democrats present Y = Number who voted Democratic that day Display the table of joint probabilities fX,Y(i,j) for 0 ≤ j ≤ i, for i=0,1,2,3. We can say that p(i,j)=P[x=i, Y=j].
