UPSEE Solved Model Paper 3

Direction : For the following questions, chose the correct answer the codes [a], [b], [c] and [d] defines as follows
Let us define a two events A and B such that 0 < P (A), P (B) < 1.
statement I : The conditional probability relation between A and B is
P(

A

B

)+P(

− A

B

) =

3

2

statement II : If the event B is already occurred, the P(

A

B

) =

P(A∩B)

P(B)

and P(

−

B

) = P (A ∩ B) + P(

−

A

∩B).
