Question

Given sample a={1,2,3,4,5} how many items are in the complement of set b is b= all numbers greater then 2?

Answer 1

If the set X is a subset of given set Y then the complement of X is the set of elements in Y but not in X.

set A = {1, 2, 3, 4, 5}

set B = {3, 4, 5}

the complement of set B: B' = {1, 2}

Answer: 2 items.

Answer 2

Answer:

There are 2 items in the complement of b

Step-by-step explanation:

Complement of a set is all items not in the set

Complement of set b is all numbers less than and including 2

Since the sample space is 1,2,3,4,5

The only numbers in the complement of  b is 1,2
