2, 3 and 5 are prime numbers but 15 is a composite number because it has more than two factors
No, they are not a set of prime numbers.
Of that list, 2, 3 and 5 are prime.
Prime numbers from 1 to 15 are 2, 3, 5, 7, 11 and 13.
The prime numbers are: 2 3 5 7 11 and 13 so therefore as a fraction of 15 it is 6/15 or 2/5 simplified
You cannot find the first 15 prime numbers by dividing by 2 and 3. This method would not identify 25 as being a composite.
No, the product of 2 prime numbers is not always even. If one of the prime numbers is 2, then the product will be even. However, if both prime numbers are odd, then the product will be odd.
3, 7 and 47 are prime numbers. 30 is not a prime since it is divisible by 2, 3, 5, 6, 10 and 15.
There are six prime numbers that are less than 15: 2 3 5 7 11 and 136 of them.
2 3 5 7 11 13 15
The product of the prime numbers 3 and 5 is 15.
15 because 5 and 3
Prime numbers from 1 to 15 are: 2 3 5 7 11 and 13 So the probability is: 6/15 or as 2/5
