Document Summary
How many of the integers x with 1 x 120 are divisible by at least one of 2 or 5: 60, 84, 12, 72, 96. How many of the integers x with 1 x 120 are divisible by at least one of 2, 3, or 5: 4, 40, 76, 108, 112. How many ways are there to rearrange the list (1, 2, 3, 4, 5) such that 1, 3, and 5 do not wind up in the same place: 2! = 120 120 + 60 20 + 5 = 45: 5! = 120 72 = 48: 5! = 120 72 + 18 2 = 64: 5! Let s be a set with three subsets a, b, and c. suppose that x is an element of s. how many of the sets. Answer as precisely as possible: 1, 1 or 7, 1, 3, or 7, an odd number, any number between 1 and 7.
