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
