1. The problem statement, all variables and given/known data Use probability trees to determine the probability of obtaining,in a deck of cards: two red cards (A-10 hearts or diamonds) and two picture cards (any suit) in any order? 2. Relevant equations 3. The attempt at a solution P(1st red card)= 20/52 P (2nd red card)=19/51 P(1st picture card) = 12/52 P(2nd picture card)=11/51 How would you combine these together to get the solution? Do you use joint probability?
