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
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}
