I remember us doing these problems in class together, but for numbers 23-36 in section 13.1, what is it exactly asking to do? I'm getting confused and there's no example to support it.
Also, for number 21, is there any other easier method besides thinking about and listing everything in your head?
How would you do number 39 in 13.2? it is similar to number 35, where the answer is in the thousands. How do they get such a big number?
can someone explain how to do number 37 in 13.1?
Never mind, I got numbers 23 and 25. (I actually meant numbers 23-26, but said 36 instead. its just using the counting formula!). If anyone can answer my other questions though, I would appreciate it.
What I tried to do was actually make a 3-circle venn diagram and work from there. I got the answers to some of the things they asked, but not all. I don't know if that's the most effective metod, so I don't know if it will work for everyone.
It's MUCH easier if the venn diagram is given to you, like how it is in the review section!
