Question

OMG HOW CONFUSING SOMEONE HELP ME PLEASSEEE Suppose {1, 2, 3, 4, 5, 6, 7, 8} A = {1, 3, 5, 7} B= {4,5,6} is A subset B? Is B subset U?

Answer 1

a subset of B - "Does all values of A seen in B"? No
b subset of U - "Does all values of B seen in u"?______

Answer 2

Ok this is confusing me so subset a seen in b means they arent there because its what is missing then the set b would be in u because it is in the set

Answer 3

Can someone break this down so I can understand exactly what I am getting confused on?

Answer 4

subset means "is it a part of"

so the first ques is A subset B
A = {1, 3, 5, 7}
B= {4,5,6}

so ques is "is A a part o B - that answer is NO since 1 3 5 7 are not in B

makes more sense?

Answer 5

If A and B are sets and every element of A is also an element of B, then A is a subset of B
