Step-by-step explanation:

1) A∪B={1,2,3,4,5,8,9,11,12,14,15,17,18,19}

2) A∩B = { 2,3,8,9,12,18,19}

Step-by-step explanation:

Since we have given that

A={1,2,4,5,8,9,11,12,14,15,17,18,19}

B={2,3,8,9,12,18,19}

So, we need to find the union of above sets and intersection of above sets.

Since union is the collection of all elements either in A or in B.

So, it becomes,

A∪B={1,2,3,4,5,8,9,11,12,14,15,17,18,19}

And intersection is the common element both in A and B.

A∩B = { 2,3,8,9,12,18,19}
