Black Red
What is the probability of having a black 5 then a red 4?
Keith makes up a deck of 40 cards. The cards are numbered from 1 to 10 and each number comes in 4 colors (orange, red, black, and blue). He selects cards from the deck. Once a card is selected it is NOT replaced.
Tthe chance of having a black 5 on the first pick is 1/40. The odds of the red 4 being next are 1/39 (there are only 39 cards in the deck after the black 5 is removed.)
The odds of removing them in exactly that sequence is:
1/40 * 1/39 = 1/1560
