  • #11-i
    (a) white ball, (ii) black ball (ii) black ball
    Ans : A white ball
    As there is no white ball in the bag
    ∴ Its probability is zero (0) = or P(E) = 0 (ii) black ball
    ∴ Number of favourable outcome = 1
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 1/6 (ii) black ball
    ∴ Number of favourable outcome = 1
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 1/6
  • #11-ii-a
    black ball
    Ans : black ball
    ∴ Number of favourable outcome = 1
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 1/6
