Consider the Venn diagram below. The numbers in the regions of the circle indicate the number of items that belong to that region.
(2 intersecting circles A & B, where A part is 50, B part is 110, and the intersecting part is 40)
Determine:
n(A)
n(B)
P(A)
P(B)
P(AB)
P(BA)

Mithra asked you what P is. You didn't respond.

im not sure what P is....

P is probability: P(AB) reads probability of event A given event B.
