`(P uu Q)uu R=P uu(Q uu R)`

In the Venn diagram,the numbers represent the number of elements in the subsets.Given that xi=P uu Q uu R,n(P')=13 and n(P uu Q)=18, find n[(P uu R)nn Q']

If P={1,5,7,10},Q={5,10,12,17} and R={1,10,12,18,21} find (i)P uu Q(ii)Q uu R

A = (A nn B) uu (AB) and A uu (BA) = (A uu B)

Let P = {1,4,9} and Q={2,4,6}. Write the elements of (P nn Q) xx (P uu Q) . Also, find (P xx Q) nn (Q xx P)

For any two events A and B; Prove that exactly one of the A; B occurs is given by P(A)+P(B)-2P(A uu B)=P(A uu B)-P(A nn B)

Let A and B be two events of random experiment such that P(A') = 0.3, P(B) = 0.4 and P( A nn B' ) = 0.5, then P(A uu B) + P(B|A uu B') = ____

Which of the following are corect: 1. A-B=A - (Ann B) 2. A = (A nnB) uu (A-B) 3. A - (B uu C) =(A-B) uu (A-C)

A uu B = (AB) uu (BA) uu (A nn B)
