1. The problem statement, all variables and given/known data In a deck of 52 cards, one black card is removed. There are then 13 cards dealt. Show that the probability that they are all red is 2/3. 3. The attempt at a solution I don't understand why I can't calculate the probability as That is, the the number of red cards when total cards is 51 divided by this total, times the number of red cards, given that one was drawn previously, divided by the new total of 50, etc. etc. But this value isn't even close to 2/3! Apparently it's more like 13/(1 740 081) How can I increase my denominator by several hundred thousand to get 2/3?
