The numbers 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99 and 100 are composite (including the boundaries).
All numbers between 80 and 100 except 83, 89, and 97 are composites.
All of them except for 83, 89 and 97 which are prime numbers
The composite numbers between 70 and 80 are 72, 74, 75, 76, 77 and 78.
All even numbers between 50 and 80 are composite.
Out of those 100 numbers, 21 of them are prime numbers, so the remaining (100 - 21) = 79 are composite.
All numbers between 80 and 100 except 83, 89, and 97 are composites.
