    In a single throw of a die, find the probability of getting a number (i) greater than 2 (ii) less than or equal to 2 (iii) not greater than 2. (i) greater than 2 (ii) less than or equal to 2 (iii) not greater than 2.
    Ans : (i) A die has six numbers = 1, 2, 3, 4, 5, 6
    ∴ Number of possible outcomes = 6
    ∴ P(E) = 4/6 = 2/3 (ii) Less than or equal to 2
    Number of favourable outcome = 1, 2
    ∴ P(E) = 2/6
    = 1/3 (iii) Not greater than 2
    Number of favourable outcomes = 1, 2
    ∴ P(E) = 2/6
    = 1/3 (i) A die has six numbers = 1, 2, 3, 4, 5, 6
    ∴ Number of possible outcomes = 6
    ∴ P(E) = 4/6 = 2/3 (ii) Less than or equal to 2
    Number of favourable outcome = 1, 2
    ∴ P(E) = 2/6
    = 1/3 (iii) Not greater than 2
    Number of favourable outcomes = 1, 2
    ∴ P(E) = 2/6
    = 1/3
  • #6-i
    greater than 2
    Ans : A die has six numbers = 1, 2, 3, 4, 5, 6
    ∴ Number of possible outcomes = 6
    ∴ P(E) = 4/6 = 2/3
  • #6-ii
    less than or equal to 2
    Ans : Less than or equal to 2
    Number of favourable outcome = 1, 2
    ∴ P(E) = 2/6
    = 1/3
  • #6-iii
    not greater than 2.
    Ans : Not greater than 2
    Number of favourable outcomes = 1, 2
    ∴ P(E) = 2/6
    = 1/3
