composite numbers are less than 12: 4, 6, 8, 9, 10
The sum of the composite numbers that are less than 8 is: 4+6 = 10
ANSWER: The composite numbers between 5 and 10 are 6, 8 and 9.6 is a composite number because the factors of 6 other 1 and itself (6) are 2 and 3.8 is a composite number because the factors of 8 other 1 and itself (8) are 2 and 4.9 is a composite number because the factor of 9 other 1 and itself (9) is 3.
The probability of rolling a composite number on a 6 sided die, numbered 1, 2, 3, 4, 5, and 6, is 1 in 3. There are two composite numbers on the die, 4 and 6. The others are prime, 2, 3, and 5, or unity, 1, so there are 2 possible outcomes in an possible result set of 6, hence the probability is 2 in 6, or 1 in 3.
A composte number is any number that is not prime. The numbers 1, 2, 3, 4, 5 and 6 appear on a die. 2, 3 and 5 are prime numbers; and one 1 is niether prime nor composite (unit). Therefore, 4 and 6 are composite. So the probability or rolling a composite number is 1/3 (2/6).
