Try and understand using the venn diagrams
yup , its easier to understand with venn diagrams
i understood the first 2. i didnt really want to understand the (iii)
A+B+C we get everything, but extra too
A+B gives us a A∩B extra, so we take that out
in A+B+C, extra is the 3 intersection parts
When we take out A∩B, B∩C and C∩A in A+B+C, we also take out A∩B∩C
so we add it back once
that's how the formula works, u can easily understand it using the regions of venn diagram

@Deleted User ek aur baat ye hai ki ye sabhi formula Probability ke liye bhi apply hote so win win situation if you understand them
yea yea, dont mug up them, if u understand them , there is some use of venn in probablityy
Arey buddy theses formulas are like the properties of numbers... Like how 5+(7+8) = (5+7)+8, same way remember these properties...Maths me rattu mat bano nahi to Chatur ban jaoge... Formula ke related 30-40 questions laga le bhai aaraam se yaad ho jaega
