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. |
