Just count them - there are not THAT many of them.
The only numbers that fit the criteria of being greater than 76 but not less than 89 are the integers starting from 89 onwards. Thus, the numbers that are greater than 76 but not less than 89 are 89, 90, 91, and so on, extending infinitely. Since there is no upper limit specified, there are infinitely many numbers that meet this condition.
The prime numbers that are greater than 80 and less than 100 are 83, 89, and 97.
Twelve numbers exactly are greater than 76 and less than 89.
3 composite numbers, 21, 22, and 24, are greater than 20 but less than 25.
There are 15 composite numbers greater than 50 but less than 70
