  • #9-i
    8 (ii) (a) number greater than 8 (iii) (a) number less than 8
    Ans : Number of favourable outcome = 0
    (∵ 8 is not possible)
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 0/6 = 0 (ii) Number greater than 8 will be 0
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 0/6
    = 0 (iii) Number less than 8 wil be 1, 2, 3, 4, 5, 6
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 6/6
    = 1
  • #9-ii
    (a) number greater than 8
    Ans : Number greater than 8 will be 0
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 0/6
    = 0
  • #9-iii
    (a) number less than 8
    Ans : Number less than 8 wil be 1, 2, 3, 4, 5, 6
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = 6/6
