i have a test tomorrow and im still not sure how to do this. can you please help me?
p={a,b,c}
Q={a,c,d,f}
Q-P=?
Q-P is members of Q which are not members of P, so
Q-P = {d,f}
Thankyou steve :)
but what about the 'b'?
Of course, I'd be happy to help you with this question! Let's break it down step by step.
To find the set Q-P, we need to subtract the elements of set P from set Q. In other words, we need to find the elements that are in set Q but not in set P.
Here's how you can do it:
1. List all the elements in set Q: {a, c, d, f}.
2. Identify the elements in set Q that are also in set P. In this case, we see that both set Q and set P have the element 'a' and 'c'.
3. Remove these common elements from set Q.
4. After removing 'a' and 'c', the remaining elements in set Q will be the elements that are in Q but not in P.
5. Therefore, Q - P = {d, f}.
So, the set Q-P is {d, f}. These are the elements that are in set Q but not in set P.
I hope this helps! Let me know if you have any further questions. Good luck on your test!
