In ` A B C ,P` is an interior point such that `/_P A B=10^0/_P B A=20^0,/_P C A=30^0,/_P A C=40^0` then ` A B C` is (a) isosoceles (b) right angled (c) obtuse angled

If A and B are two events such that P(A) = 0.4, P(B) = 0.8 and P(B//A) = 0.6 , then P(barA nn B) is

If in A B C , side a , b , c are in A.P. then (a) B > 60^0 (b) B<60^0 (c) Blt=60^0 (d) B=|A-C|

If A and B are two events such that P(A)=0.3 , P(B)=0.25 , P(AnnB)=0.2 , then P(((A^(C ))/(B^(C )))^(C )) is equal to

If A and B are two events such that P(A)=0.25 , P(B)=0.05 and P(AnnB)=0.14 , then P(AuuB)= ............

If A and B are two events such that P(A uu B) = 0.7, P(A nn B) = 0.2, and P(B) = 0.5 , then show that A and B are independent.

Let A,B,C be 3 events such that P(A//B)=(1)/(5) , P(B)=(1)/(2) , P(A//C)=(2)/(7) and P(C )=(1)/(2) , then P(B//A) is

A and B are events such that P(A) = 0.42 , P(B) = 0.48 and P(A and B) = 0.16 , Determine (i) P(not A), (ii) P(not B) and (iii) P(A or B).
