### Probability & Counting Methods

The word "OR" in probability indicates which operation Addition
What is the probability of an event that is​ impossible? 0
Suppose that a probability is approximated to be zero based on empirical results. Does this mean that the event is​ impossible? No
True or false​: In a probability​ model, the sum of the probabilities of all outcomes must equal 1. True
In​ probability, a(n)​ ________ is any process that can be repeated in which the results are uncertain. experiment
If E and F are disjoint​ events, then P(E or F)= ______________. P(E) + P(F)
If E and F are not disjoint​ events, then​ P(E or F)equals=​_____________________. P(E) + P(F) – P(E and F)
Two events E and F are​ _____________ if the occurrence of event E in a probability experiment does not affect the probability of event F. independent
The word and in probability implies that we use the​ ______________ rule. multiplication
True or false: When two events are​ disjoint, they are also independent. False
The notation p(F|E) means the probability of event__ given event __ F, E
A___ is an ordered arrangement of r objects chosen from n distinct objects without repetition permutation
A___ is an arrangement of r object chosen from n distinct objects without repetition and without regard to order combination
In combination problem, order is not important True or False True
In a probability model, the sum of the probabilities of all outcomes must equal 1 True or False True
In probability a(n) _ is any process that can be repeated in which the results are uncertain. experiment
Two events E and F are _ if the occurrence of event E in probability experiment does not affect the probability of event F independent

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
