Hello, I need some help with the following problem:
Exercise 2.15 of Hogg & Craig 5th edition
Five cards are drawn at random and without replacement from a bridge deck. Let the random variables X1, X2 and X3 denote, respectively, the number of spades, the number of hearts, and the number of diamonds that appear among the five cards.
A. Determine the joint p.d.f. of X1, X2 and X3.
B. Find the marginal probability density functions of X1, X2, and X3.
C. What is the joint conditional p.d.f. of X2 and X3, given that X1 = 3?
Thanks for any help provided,
Where is your work?
