Hypergeometric distribution

Task

You have a deck of 52 cards (4 of the 52 cards are aces). Then you randomly sample 5 cards without putting them back. Calculate the probabilities of getting...
  • exactly 2 aces.
  • less than 4 aces.
  • more than 1 ace.
  • 1 to 3 aces.

Instructions

1.Select the Hypergeometric Distribution from the drop-down list. Note: A table providing the probabilites P(X  k) for is created automatically.
2.Change the population to 52, since there are 52 cards in the deck.
3.Change the parameter n to 4, since there are 4 aces in the deck.
4.Change the sample to 5, since you randomly sample 5 cards.
5. Use the table to determine the probability P(X = 2).
6.Calculate the probability P(X 3) using the Left Sided button. Note: 'Less than 4' means '3 or less aces'.
7. Calculate the probability P(2 X) using the Right Sided button. Note: You need to determine the sum of the probabilities of getting 2 or more aces.
8.  Calculate the probability P(1  X  3) using the Interval button.
