Determine whether set b is a subset of set a.
a={0,1,2,3,4}
b={1,2}

B is a subset of  set A  because every element of set B is contained in set A

Step-by-step explanation:

The answer to this question is:

B is a subset of  set A  because every element of set B is contained in set A.

We can denote it as B⊆A

Subset:

A subset is a set of elements that are also in another set.  Another way to define a subset is: B is a subset of A if every element of B is contained in A.

It is denoted by B⊆A
