7. Determine whether each of the following sets is countable or uncountable. For those that are countably infinite, show that there is a one-to-one correspondence between the set of positive integers and that set. a. Integers not divisible by 3 b. Integers divisible by 5 but not 7 c. The real numbers between 0 and 2 d. The integers with absolute values less than 1.000.000 7.
