There are 4 numbers that are prime between the number 10 and 20. They are 11, 13, 17, and 19.
20 is not a prime number because 5 and 4 10 and 2 can also go into 20 not just 20 and 1
11,13,17,19
20 cannot be prime because prime numbers will only have a factor 1, whereas 20 has: 1 x 20 2 x 10 4 x 5 Thus 20 is composite
