Seven of them.
The first five composite numbers are 4, 6, 8, 9 and 10; and their sum is 37 also 28
There are many, many more composite numbers than prime numbers. For example, beyond the number 3, every other number is composite, as it is divisible by 2. Following this, every number ending with a 5 other than 5 itself is composite, as it is divisible by 5, and every third odd number is divisble by 3. There are many complicated divisibility tests for numbers above 5.
average of first five prime numbers = 5.6 first five prime numbers = 2, 3, 5, 7, 11average = sum of first prime numbers/5= (2 + 3 + 5 + 7 + 11)/5= 28/5= 5.6
