  • #2
    A coin is tossed. What is the probability of getting: (i) (a) tail?(ii) ahead?
    Ans : On tossing a coin once,
    Number of possible outcome = 2 (i) Favourable outcome getting a tail = 1
    ⇒ number of favorable outcome = 2
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = ½
    (ii) a head
    Similarly, favourable outcome getting a head = 1
    But number of possible outcome = 2
    ∴ P(E) = (Number of favourable outcome)/(Number of all possible outcome)
    = ½
