Answer 1

Part A: 24

Part B: 256

Explanation:

Part A

Without Repetition means that once you use a number out of the given four, it can't be used again.

• So the first number can be chosen 4 different ways.
• The second number can be used 3 different ways.
• The third number can be chosen 2 different ways
• And the last number has only 1 way to be chosen.

Answer: 4*3*2* 1 = 24

Part B

Part B allows repetition. That means that the numbers can be used as many as 4 times.

Answer: 4*4*4*4 = 256
