1.
Formula for combinations: n!/((n-r)!*r!)

2.
Formula for permutation: n!/(n-r)!

3.
Formula to Count Permutation w/ Like objects: nPn/p!*q!

4.
Fundamental Counting Principle: if an event can happen in N ways, and another, independent event can happen in M ways, then both events together can happen in N x M ways.

5.
Law of large-numbers: as an experiment is repeated over and over, the empirical probability of an event approaches the actual probability of the event

6.
Mutually exclusive events: Two events that cannot occur at the same time.

7.
Overlapping events: events that have one or more outcomes in common

8.
What are dependent events?: events in which the occurrence of one affects the number of possible outcomes of the other

9.
What are dependent events?: events if the occurrence of the first does affect the probability of the other

10.
What are independent events?: events if the occurrence of the first does not affect the probability of the other

11.
What is a grouping of objects in which the order of the objects does not matter?: combination

12.
What is an arrangement in which order matters?: a permutation

13.
What is a sample space?: the set of all possible outcomes

14.
What is a single event?: single outcome of an experiment

15.
What is experimental probability based on?: what has happened, actual experiment

16.
What is the formula for geometric probability?: P(A) = Area of favorable region/Area of total region

17.
What is theoretical probability based on?: what should happen, mathematical probability?

18.
What is the probability for dependent events?: P (A and B) = P(A) * P (B|A)

19.
What is the probability for independent events?: P(A and B) = P(A) * P(B)

20.
What is the probability for Mutually Exclusive Events: P(A or B) = P(A) + P(B)

21.
What is the probability of overlapping events?: P(A or B) = P(A) + P(B) - P(A and B)

Print the PDF. Fold each page down the middle along the dotted vertical line and cut the solid horizontal lines.

If your printer has a special "duplex" option, you can use it to automatically print double-sided. However for most printers, you need to:

**Print the "odd-numbered" pages first**- Feed the printed pages back into the printer
- Print the "even-numbered" pages

**If your printer prints pages face up**, you may need to tell your printer to reverse the order when printing the even-numbered pages.

Please use the "Open PDF" button to print your set.

**Why?**
In order to provide a consistent printing experience across different computers and web browsers, we've provided a standard PDF format for you to print.
