You know 120 is a composite number because it is an even number that is greater than 2.

it is a composite number because you can tell from the 8 that it is an even number, and even numbers can always be divided.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 787 is prime.

Let say the dice has n sides

Let first search for the probability to roll a number less or equal to 2

Probability to roll a 1 = 1/n

Probability to roll a 2 = 1/n

Probability to roll a 1 OR a 2 = Probability to roll a 1 + Probability to roll a 2

= 1/n + 1/n = 2/n

Probability to roll a number greater than 2 = 1 - (Probability to roll a 1 OR a 2)

= 1 - 2/n = (n-2)/n

If n = 6 then the result is (6-2)/6 = 4/6 = 2/3

It is neither because 1 has only one factor and that is itself.

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97

That is because the concept of primeness or compositeness are defined only for integers which are larger than 1.

819 is composite. 819 = 3 * 3 * 7 * 13 = 32 * 7 * 13

1,470 is a composite number. All even numbers are composite except the number two (2) which is prime.

1 is not a composite number. A composite number has more than two positive integer factors. The number 1 has just a single fraction - itself.

However, it is not a prime number, either. A prime number has exactly two positive integer factors - itself and 1.

When referring to positive integers, prime means having only two factors and composite means having more than two.

The last digit is a 2 which implies that the number is divisible by 2. So 46832 is not prime, it is composite.

A prime number can never be composite in any case. There is an exception for 2 which is both.

The number 98 is a composite number because it can be divided into 2 equally and the answer would be 49. Hoped this helped.

the both have numbers called factors

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 287 is composite.

They are members of the infinite set of numbers of the form 86*k where k is an integer. Since the set is infinite, it is not possible to list them.

675 is divisible by 5 in addition to 1 and itself. It is a composite number.

46 = 1 x 2 x 23, so it is composite. It has factors other than itself and 1.

The answer to this one is quite long and complex There fore I have added a related link (Race and ethnicity in the United States Census) below which will take you to wikipedia where there is a fairly comprehensive answer to this question.

There is no name for numbers which are neither prime nor composite.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.

yes because the last numbercan give you a clue.So 17 is a composite.
