Yes, I do agree with Jamie.
1 is NEITHER a prime number NOR a composite number.
Reason for agreeing:-
We know that a PRIME NUMBER is any given number that has only one as a factor. I.e it is only divisible by 1 AND ITSELF.
And, a COMPOSITE NUMBER is any number that is divisible by a number other than one and itself.
Here in the case of 1, we see that it is divisible by 1 and itself, and since it cannot have any other factor we can't put in either of the two categories
