None. A number that ends with 8 is even, that is, divisible by 2. ================================ To be prime a number must only be divisible by itself and 1 thus any number divisible by 2 can not be a prime number. Therefore the answer to your question is:- "There are no prime numbers between 20 and 200 that end with an 8".

The odds of choosing a prime number in the set [1-20] are 8 out of 20, as there are 8 prime numbers, 2, 3, 5, 7, 11, 13, 17, and 19, in that set.

8: 1,2,3,5,7,13,17,19

53 is prime, and 5+3 = 8.

A prime number is one which cannot be evenly divided by any prime number 61 ÷ 2 = 30 +1 61 ÷ 3 = 20 +1 61 ÷ 5 = 12 +1 61 ÷ 7 = 8 + 5 As the square root of 61 lies between 7 and 8, there is no need to take the division further than this... any prime number which might have divided it would give a result lower than the number we have already tried. So, yes! 61 is a prime number.
