Prove that
`(bar(A.B)).(A+B)=A.barB+barA.B`

If A and B are independent events only associated with a random experiment; then prove that (barA and B); (A and barB); (barA and barB) are also independent events.

If A and B are independent events, then Prove that P(AcupB)=P(Acap B)+ P(Acap barB)+ P(barA capB)

bar(A.barB+barA.B) is equivalent to

bar(A.barB+barA.B) is equivalent to

Prove that P(A cup B) = P(A cap B)+P(A cap barB)+P(barA cap B)

Let barA,barB and barC be unit vectors such that barA.barB=barA.barC =0 Angle between B and C is 60°. If barA=k(barBxxbarC), then : k=

If barA and barB are the events complementary to the events A and B respectively, prove that, P(barA or barB)=1-P(A)P(B//A) .
