यदि A और B दो घटनाएँ इस प्रकार हों ताकि `P (A uu B)=P(A)` तो

PA and PB are two tangents from a point P outside the circle with centre O. If A and B are points on the circle such that angle APB = 128^@ , then angle OAB is equal to: PA और PB, O केंद्र वाले वृत्त के बाहर एक बिंदु P से दो स्पर्शरेखा है । यदि A और B वृ पर बिंदु इस कार है की है angle APB = 128^@ , तो angle OAB बराबर है:

If A and B are two events such that P(A uu B) + P(A nn B) = (7)/(8) and P(A) = 2P(B) , then P(A) =

If A and B are two events such that P(A uu B) + P(A nn B) = (7)/(8) and P(A) = 2P(B) , then P(A) =

The following question consist of two statements, one labelled as the 'Assertion (A)' and the other as 'Reason (R)' You are to examine these two statements carefully and select the answer. Assertion (A) : If P(A) = 3/4 and P(B) = 3/8, then P(A uu B) ge 3/4 Reason (R) : P(A) le P(A uu B) and P(B) le P(A uu B) , hence P(A uu B) ge " max ". {P(A), P(B)}

If A={a,b},B={b,c} Find P(A), P(B), P(A) uu P(B) , P(A) nn P(B) show that P(A) uu P(B) sub P(A uu B)

Is it true that for any sets A and B, P(A) uu P(B) = P(A uu B) ? Justify your answer.

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') = ____
