A universal set U consists of 15 elements. If sets A, B, and Care proper subsets of U and n(U) = 15, n(AB) = n(An C) = n(BNC)=7, n( ABC) = 4, and n(A
UBU C) = 13, determine each of the following.
a) n(AUB)
b) n(AUC)
c) n(
AB)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
