I have no strong background in Probability, please, present to me an easy to understand solution to this problem with detail explanation. Thank you.
An urn contains three white, six red, and five black balls. Six
of these balls are randomly selected from the urn. Let X and Y
denote
respectively the number of white and black balls selected. Compute
the conditional probability mass function of X given that Y = 3.
Also compute E[X|Y = 1]
