Question

4. (09.01 MC) Let set A = {1, 3, 5, 7) and set B = {1, 2, 3, 4, 5, 6, 7, 8} Which notation shows the relationship between set A and set B? (2 points) O AUB O ASE O Ane OBCA

Answer 1

A set X is said to contain a set Y if every element in Y is an element in X.

`X\supseteq Y\text{ or X}\subseteq Y`

In this case

`1\in B,\text{ 3 }\in B,5\in B,\text{ and 7}\in B`
`\in\text{ means: is in}`
`so\text{ m}\in N,\text{ means that m is in N}`

Therefore,

`B\supseteq A\text{ or A}\subseteq B`
