Given:
Set A containing factors of 15.
This can be represented in roster form: {1,3,5}
Set B containing prime numbers less than 10.
This can be represented in roster form: {1,2,3,5,7}
Find AUB.
U means the union between two sets. The elements of the first set is combined with the elements of the second set.
AUB = {1,2,3,5,7}
