U = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20}
A = {3,6,9,12,15,18}
B = {4,8,12,16,20}
B' = set of elements of U that are not in B ={1,2,3,5,6,7,9,10,11,13,14,15,17,18,19}




Count those numbers of elements and make those fractions.  Reduce the fractions if
possible.

In English, there is no such combination of words "the possibility space".

It is bad incorrect translation from other language; it is not used in English.

What you call here "the possibility space", has the correct name "space of events".


When you compose Math problems on your own,
check your terminology using GOOGLE translator.
