Thank you for teaching me these methods. I was faced with these types of problems in a geometry book (about dogs, strangely), and after struggling for over an hour, I watched one of your videos, went back and easily solved the problem. On this problem, I did it a different way, but it still worked. I used the rather lengthy equation: 33 - [(17-x) + x + (13-x)] + 25 - [(17-x) + x + (16 -x)] + 27 - [(16-x) + x + (13-x)] = 26. I found the 26 (tourists who had only been to one city) by subtracting the 50 who had not been to any cities from the 76 who had been to at most one city. Now that I have watched this video, I know there may be more efficient options.
It helped me after 8 years of you uploading, may be it took some time to reach India 😂 nicely explained btw thankyou
Thank you so much,,,, you have really helped me to solve the problem on venn diagrams
Glad to hear that!
What if the value of U is unknown?
Very Nice,Thanks for uploading such a nice video.
I am glad that you liked it! Thanks for watching.
Thanks so much this seriously helped!!

I am glad the video helped. I like the way you solved the problem. Personal methods are always the most meaningful ones.
Are you a university or a high-school student?
Yeah, that's when you feel like you are really understanding the concepts.
Neither. I am doing my own studies. Also, I am tutoring GED students for the math part of the test.
That is wonderful.
Too complicated🤔🤔🤔
