If you put 5 which means its 2 1/2 ( I think) Because two 1/2 makes one.
hope it will help you..........
P(a U b) = p(a) + p(b) - p(a ∩ b)
<=>
p(a ∩ b) = p(a) + p(b) - p(a U b)
I let you do the maths :)
Well sir according to my calculations if you have a 3 and than you add 3 to the 3 you already have then you would end up with the exact answer of number 6
