If 
and 
are the complementary events of E and F respectively and if 0 < P (F) < 1 . then
and are the complementary events of E and F respectively and if 0 < P (F) < 1 . then Options
A.P(E / F) + P( / F) = 1
/ F) = 1B.P(E / F) + P(E / ) = 1
) = 1C.P( / F) + P(E / ) = 1
/ F) + P(E / ) = 1D.P(E / ) + P( / ) = 1
) + P( / ) = 1Solution
(a) P(E / F) + P( / F)
Therefore (a) is correct.
(b) P(E / F) + P(E /)
Therefore, (b) is not correct.
(c) P( / F) + P(E / ) = 
Therefore, (c) is not the answer.
(d) P(E /) + P( / )
= 1
Therefore, (d) is true.
So, (a), (d) are the answers.
/ F)Therefore (a) is correct.
(b) P(E / F) + P(E /
)Therefore, (b) is not correct.
(c) P(
/ F) + P(E / ) = Therefore, (c) is not the answer.
(d) P(E /
) + P( / )= 1Therefore, (d) is true.
So, (a), (d) are the answers.
