The odd prime numbers less than 20 are 3, 5, 7, 11, 13, 17, and 19.
It is 75.
NO!!!! By the fact that it is an EVEN number, it is a compound number number, with a factor of '2'. . Since it is a factored compound number , then it is NOT a prime number. NB. Except for '2'. there are no EVEN prime numbers. All Prime numbers are ODD. However, not all odd numbers are prime number. Here is a list of number to '20'. 1,2,3,4,**5,**6,7,8,9,10,11,12,13,14,15,16,17,18,19,& 20 2,3,5,7,11,13,17, 19 Are prime numbers. This leaves 9,15, which are ODD numbers, but NOT Prime numbers, because ;- 3 x 3 = 9 and 3 x 5 = 15 are compound odd numbers. NB The list of numbers and prime numbers beyond '20' is inexhaustive.
Seven of them.

NO!!!! Other than '2' all prime numbers are odd numbers. 4,6,10 & 20 are all even so they are not prime numbers.
All the numbers from 2 to 19 are multiples of prime numbers.
2 x 2 x 5 = 20 20 is even.
Yes - every prime number except for 2 is odd - including the primes between 10 and 20, namely 11, 13, 17, and 19.
The numbers between 10 and 20 that are not prime are 12, 14, 15, 16 and 18. So 15 is the odd number and the rest are even numbers.
Numbers that are prime can't be multiples of 10. Multiples of 10 can't be odd.
The first 20 odd numbers are: 13579111315171921232527293133353739.
There are eight prime numbers under 20.
