This principle simply tells us that if you have 2 choices to make, 1 from a list of m items and 1 from a list of n, the total number of ways to make the 2 choices is m times n. Similarly, if there are more than 2 choices, you just multiply the number of possibilities together. For example, if you have 4 choices for what your first child will wear today, 5 choices for the second, and 7 for the third, the total number of combinations is 4 times 5 times 7 which is 140. This assumes that the number of options for each choice is independent of the other choices you make. For example, if you must choose one direction to go one block in a city, and then another at the end of that block, but if you choose to go north in the first place you are at a dead end, but if you had gone south you could go 3 different directions, the principle does not apply because the number of options for the second choice depends on your first choice.

There are 220 combinations. Do you want to know why this is the answer? (It's worth knowing because this is a widely used principle in mathematics.) There are 10 digits to choose from, four of them are to be chosen at a time and a combination of four can include more any given digit more than once. So the total number of 4-digit combinations (without insisting that there be any 2s in them) is (10+4-1)choose 4= 13 choose 4 = 715. If 2s are _not_ allowed then there would be 9 digits to choose from and the total number of 4-digit combinations would be (9+4-1) choose 4 = 12 choose 4 = 495. Then the number of 4-digit combinations in which anywhere from 1 to 4 2s are allowed would be 715 - 495 = 220.

Assume you have 6 spots shown below: _ _ _ _ _ _ In the first spot, you have 6 letters to choose from. In the second spot, you have 5 letters to choose from because you already used one.
