  • question_answer
    Three coins are tossed together. The possible outcomes are no head, 1 head, 2 head and 3 heads. So, I say that probability of no head is\[\frac{1}{4}\]

    A) True

    B) False

    C) Can't say

    D) Partially true/False

    Correct Answer: B

    Solution :

    No, the outcomes are not equally likely, because outcome 'no head' means ''TTT''; and outcome 'one head' means THT, HTT, TTH and so on P(TTT) = \[=\frac{1}{8}\], which is not equal to \[\frac{1}{4}\]
