Actually, 13 and 15 are not twin primes because twin primes are pairs of prime numbers that have a difference of 2 between them. In this case, 13 is a Prime number, but 15 is not a prime number because it can be divided by 3 and 5 in addition to 1 and itself. Therefore, 13 and 15 do not meet the criteria to be considered twin primes.
