Four dice are thrown simultaneously. Find the probability that all of them show the same face.	Choose the correct answer.
A) 1/215
B) 1/216
C) 1/217
D) 2
E) 2/215
The total number of elementary events associated to the random experiments of throwing four dice simultaneously is:   =6×6×6×6=64   n(S)=64   Let X   be the event that all dice show the same face.   X={(1,1,1,1,),(2,2,2,2),(3,3,3,3),(4,4,4,4),(5,5,5,5),(6,6,6,6)}   n(X)=6   Hence required probability,   =n(X)n(S)=664   =1/216   Answer is 1/216
