. We're sorry about the hassle.
Can you write what you mean? You are currently saying that 1 is a prime.
I don't understand, why don't we put 10 as the answer too?
But 1 is not a prime number
BUT IS 1 ALSO A PRIME NUMBER ?

1 is prime!!!!!!!!!!! From where do you hear it????
all the positive integers are composite numbers except all prime numbers and 1.
so first 10 positive integers are following:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
only 4, 6, 8, 9 and 10 are composite rest are prime numbers and 1 is unit.
thus, 5 is answer.
The first 10 composite number are 4,6,8,9,10 [5] Composite number is a number that can be factorized 4 = 2^2 6 = 2 3 8 = 2^3 9 = 3^2 10 = 2 5
Composite Number is a whole number that can be divided evenly by numbers other than 1 or itself. Example: 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is a composite number. 7 can only be divided evenly by 1 or 7, so it is NOT. 4, 6, 8, 9, 10 are COMPOSITE.
1,2,3,4,5,6,7,8,9,10 compite number is amumber which has factors other than 1 or the number itself. hence, the numbers are 4,6,8,9,10
the first 10 positive integers are 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. Only 4, 6 8, 9, and 10 are composite. then the answer is 5.
1 is neither a prime nor a composite.
1-4-6-8-9-10

First 10 positive integers are 1,2,3,4,5,6,7,8,9, and 10.
remember, composite numbers are numbers that NOT A PRIME NUMBER.
So, you can take out 1,2,3,5, and 7. The rest are the answer.
