Using the group of cards just described in this lesson, the probability of drawing a red five is

The probality, p, of drawing a red five is the number of red five cards in the group divided by the total number of cards in the group:

p = number of red fives / number of cards

I will do two examples.

If all the cards are different, i. e. there is only one red-five, and there are 4 colors each with numbers 1-14, the probability will be:

p = 1 / (4*14) = 1/56

If, there is a group of regular cards, i. e. with 26 red and 26 black cards, with the numbers 1-10, plus J, Q, and K, and with two jokers:

Total number of red fives = 2 =

Total number of cards = 4*13 + 2 = 52+2 = 54

=> p = 2 / 54 = 1 / 27

So whats the answer?
