Count the Ways
  1. If you use just the aces, in how many ways can you get a heart? one
  2. If you use just the hearts, in how many ways can you get a ace? one
  3. Considering just the black cards, in how many ways can you get a heart? zero
  4. If you use just the clubs, in how many ways can you get a face card? three
  5. Considering just the aces, in how many ways can you get a ace? four


Given A Deck of Cards Count the Ways

Given a regular deck of cards,

  1. In how many ways can you get a heart? 13/52 or 1/4
  2. In how many ways can you ? 13/52 or 1/4
  3. In how many ways can you get a ace? four
  4. In how many ways can you get a face card? 12
  5. In how many ways can you get a black card? 26/52 or 1/2
  6. In how many ways can you get the King of Clubs? 1/52
  7. In how many ways can you get a card that is an ace and at the same time a club? 1/52
  8. In how many ways can you get a card that is an ace or is a club? 16/52 = 8/26 = 4/13


Count the Ways You Can Draw Two Cards Without Replacement

      Without replacement means you take a card, then, without returning it to the deck take a second card.

  1. If you use just the black cards, in how many ways can you get a ace then a two? 2x2=4
  2. Considering just the black cards, in how many ways can you get a face card then another face card? 6x5=30
  3. Considering the full deck, in how many ways can you get a face card then another face card? 12x11=132
  4. If you use just the clubs, in how many ways can you get a face card then another face card? 3x2=6
  5. Considering the entire deck, in how many ways can you get a deuce then a face card? 4x12=48
  6. Considering the full deck, in how many ways can you get a heart then a second heart? 13x12=156.


Count the Ways You Can Draw Two Cards With Replacement

      With replacement means you take a card, then, return it to the deck, then take a second card.

  1. If you use just the black cards, in how many ways can you get a ace then a two? 2x2=4
  2. Considering just the black cards, in how many ways can you get a face card then another face card? 6x6=36
  3. Considering the full deck, in how many ways can you get a face card then another face card? 12x12=144
  4. If you use just the clubs, in how many ways can you get a face card then another face card? 3x3=9
  5. Considering the entire deck, in how many ways can you get a deuce then a face card? 4x12=48
  6. Considering the full deck, in how many ways can you get a heart then a second heart? 13x13=169.


Count the Ways
  1. In how many ways can you draw 3 cards without replacement from the face cards? 12x11x10=1320
  2. In how many ways can you draw 3 cards with replacement from the face cards? 12x12x12=1728
  3. In how many ways can you draw 5 cards without replacement from the deck of red cards? 26x25x24x23x22=7893600
  4. In how many ways can you draw 2 cards from the full deck without replacement? 52x51=2652
  5. In how many ways can you draw all 52 cards from the deck without replacement? 52! 52 factorial ways, 8.0658x10^67 ways


Computing the Number of Ways to Make Ordered Lists THE EASY WAY

      All the problems on this page deal with ordered lists and the next page deals with computing probability involving ordered lists.

      There is an easy way to compute the numbers of ways to make an ordered list. It is the permutation formula (shown below). To learn of this, visit page Number of Ways to Make An Ordered List.
   
 
n!
 (number of ordered lists given n things)
Pn,x =
=
 
(n-x)!
 (shorten the list so only x things are used)
