Lots of prime numbers have zeros in them. 101, 103, 107 and 109 are all prime numbers. Prime numbers can't end in zero. Numbers that end in zero are multiples of ten and have too many factors to be prime numbers.
Square numbers can't be prime. They have too many factors.
5 is a prime number,because prime numbers only have too numbers that go into itself.those numbers are 1 and itself, in this case 5. with composite numbers it is the other way around.

The list is far too long to list here (millions of them); a search on "list of prime numbers" can quickly give you the desired prime numbers.
The sum of the numbers 1 to 100 is 5050.

1 is the only number between 1 and 100 that has too few factors to be a prime number.
Square numbers have too many factors to be prime.
Too much information to display here.
101 to 199 give 50 odd numbers. Their sum is 7,500.[I'm not too certain that the question meant 'the average total'? But, the odd numbers average total would be 7,500 ÷ 50 = 150]
too many numbers
