Question: a. How many integers from 1 through 1,000 are multiples of 4 or multiples of 7?
b. Suppose an integer from 1 through 1,000 is chosen at random. Use the result of part (a) to find the probability that the integer is a multiple of 4 or a multiple of 7.
c. How many integers from 1 through 1,000 are neither multiples of 4 nor multiples of 7?
