Question

If A and B are two events and A ≠ Φ, B ≠ Φ, then ______.

Options

  • P(A|B) = P(A).P(B)

  • P(A|B) = P(AB)P(B)

  • P(A|B).P(B|A)=1

  • P(A|B) = P(A)|P(B)

MCQ
Fill in the Blanks

Solution

If A and B are two events and A ≠ Φ, B ≠ Φ, then P(A|B) = P(AB)P(B).

Explanation:

Given that: A ≠ Φ and B ≠ Φ

Then P(A|B) = P(AB)P(B)

A bag contains 3 red and 5 white balls. Two balls are drawn at random one after the other without replacement. Find the probability that both the balls are white.

Solution: Let,

B : second ball drawn in white.

P(A) =

After drawing the first ball, without replacing it into the bag a second ball is drawn from the remaining balls.

∴ P(B/A) =
