Options:

Answer:

Solution:

(c) The probability of showing same number by both dice $p = \frac{6}{36} = \frac{1}{6}$ In binomial distribution here $n = 4, r = 2, p =$ $\frac{1}{6}, q = \frac{5}{6} req. probability =^{n} C_{r} q^{n - r} p^{r} =^{4} C_{2} (\frac{5}{6})^{2} (\frac{1}{6})^{2} = 6 (\frac{25}{36}) (\frac{1}{36}) = \frac{25}{216}$
