hey so i am wondering how would you solve these like the method i have the answers PLS help i am rlly confused.
A={factors of 12}
B={factors of 18}
D={prime numbers} the universal set is 1 to 25 inclusive
1)A ∪ B∩ C
2)A∪B∩D'
just how would you solve it if there are more than two sets where there is different notation symbols because i am unsure how to do this.

If you draw it as a Venn diagram, does the order matter? So for 1) do
(A ∪ B) ∩ C
Both operations then just involve 2 sets.

Do brackets not exist?

That's why I was a little confused 😂
ohhhhhhhhhhhh so you would bracket the first two?
So basically draw it as a venn diagram?Hold on sorry can one of you explain step by step the method

OK... So start with (AuB)nD and have a go from there
