a) how many were in dance OR swimming? my answer 123
b) yow many were in at least 1 activity? my answer 5
c) how many were in at most two activities? 151
I don't know how to draw the venn diagram on this site! Can anyone check my answers?
I really appreciate the help. I had 39 where you have 35 for dancing.
I had 8 where you have 12 for swimming and dance.
I had 72 where you have 69, and I had nothing in the U.
Close only counts in horse shoes - right?
Please tell me where you found the venn? Is it something I can do?
Hello j-ramI'm not quite sure how you got your answers. Do you understand how I got mine? I started right in the middle (9), then work outwards - there are 21 doing dance and swimming, so subtract 9 from 21, to get 12, and so on.I don't understand what you mean here. Perhaps we use different words for this!Close only counts in horse shoes - right?
I drew the Venn diagram in CorelDraw, and saved it as a .jpg, before using the 'Manage Attachments' button to attach it to the posting.Please tell me where you found the venn? Is it something I can do?

I have not heard the professor say work from the inside out. That did help. I just plugged in numbers and tried to make them "work". Do you play horseshoes in UK? If a horseshoe gets close to the stake, we let it count as a ringer. I do not know if this is a real rule, or not! My pun refered to my numbers being "close" to yours. Thank-a-million!
