    A dice is thrown two times. If getting the odd number is considered as success, then the probability of two successes is

    A)                 \[\frac{1}{2}\]       

    B)                 \[\frac{3}{4}\]

    C)                 \[\frac{2}{3}\]       

    D)                 \[\frac{1}{4}\]

    Correct Answer: D

    Solution :

               Probability of getting odd number \[=\frac{3}{6}=\frac{1}{2}\]                 Hence required probability \[={}^{2}{{C}_{2}}{{\left( \frac{1}{2} \right)}^{2}}{{\left( \frac{1}{2} \right)}^{0}}=\frac{1}{4}.\]
