Two dice are rolled simultaneously. What is the probability that 6 will come up at least once?\

Question

Professor PC Thomas Classes · Answer

(c) : When two dice are rolled simultaneously then sample space $n(S)=36$\ Number of event in which 6 will come up at least once is;\ $E=\{(1,6),(6,1),(2,6),(6,2),(3,6),(6,3),(4,6),(6,4),(5,6)$, $(6,5),(6,6)\}$\ $	herefore \quad n(E)=11$\ So, required probability, $P(E)=\frac{n(E)}{n(S)}=\frac{11}{36}$
