i want venn diagram formulas?

Answer 1

there is nothing such as a "venn diagram" formula.i think that what u are looking for here is De Morgan's laws.a venn diagram is only drawn to aid u in getting to a solution but it wont be required once u get to understand things a bit better.
P(AnB)=P(A)+P(B)-P(AuB)
P(A*)=1-P(A) where A* is the complement of A
P(S)=1 where S is the sample space

Answer 3

I am assuming that no person simultaneously has blue and brown eyes and that a person can be colorblind with either blue or brown eyes and that this is a complete set of the possibilities. If you add together 286, 560, 93, and 138 the total is 1077, 77 greater than the total number in the study. Since the only possible point of overlap is being colorblind and having either blue or brown eyes, the answer is 77.

Go to 'www.purplemath.com' and click on 'lessons index' in the upper right corner of the home page. On the 'lessons index' screen scroll to the bottom and on the lower right corner click on Venn Diagrams and you'll find what you need. It's a super site for algebra related info. Great explanantions!

Answer 5

n(aub)=n(a)+n(b)-n(a int b)
n(au b u c)=n(a)+n(b)+n(c)-n(a int b)-n(b int c) - n(c int a)+
n(a int b int c)

Answer 6

n(AUB)=n(A)+n(B)-n(AintersectionB)
n(AintersectionB)=n(A)+N(B)-N(AUB)
