Question

If A={x:x=4n+1,n≤5, n∈N} and B={3n:n≤8, n∈N} then find (A∪B)-(A∩B)

Answer 1

Answer:

{3,5,6,12,13,15,18,17,24}

Step-by-step explanation:

first we will write both set A and set B in roster form

A={5,9,13,17,21}

B={3,6,9,12,15,18,21,24}

now A union B={3,5,6,9,12,13,15,18,17,21,24}

A intersection B={9,12}

and the final answer is above.
