You have made my understanding of sets and probability more sharper. Thank you sir. Now I can confidently teach my learners probability with 150% confidence.
Hi. I'm sorry something is not coming through clearly. I dont think your full comment is visible. Can you try asking it again? I'm not sure what the issue is.
I think I found your whole comment. Right off the top of my head (A union B) intersects (not(A intersection B)). That can probably be written simpler but it would depend on the notation you are using.
Mr. Jeremy ,i think that the Q(c) on 27:29 minutes of the video ,C) ON THE YEARBOOK COMMITEE BUT NOT THE STUDENTS' COUNCIL , THE ANWSER SHOULDN BE 4 * 7-3 =4 PLZ CHECK ON THAT SIR
Well A union not B would be if we first shaded in set A completely including the part where it overlapped with B. Then we would shade in not B which is everything outside of set B, including the part of A that doesn't overlap with B. What we are left with is the cookie with a bite out of it shape in set B that doesn't overlap with A. Then we subtract set B, meaning we erase the shading in set B... this is the part that overlaps with set A. What you get in the end is exactly not B, I think.
@zeroossi5967 just for clarification, when you say contain, are you saying that b is a proper subset of not a? If so then your conclusion isn't necessarily true. Your original union is simply the part of set b that isn't in the intersection with set a.
