    set union P U Q which means all numbers in set P or all numbers in set Q. It's all of the numbers (you don't have to write the same number more than once if it's in set P and set Q)

    set intersection -> |dw:1438766135691:dw| means what does set P and set Q have in common. The numbers 8,9,10 are in set P and set Q so this is set intersection so for set union yes... b is the answer.
