Suppose that we roll two fair 6-sided dice. What is the probability that the two numbers rolled sum to 4?

1 Answer

#1/12#

Explanation:

Favorable outcomes/results to get a sum of #4# when fair dices are tossed are

#(1, 3), (2, 2), (3, 1)#

While, the total outcomes of two fair dices #=6\times6=36#

hence, the probability to get a sum of 4

#=\frac{\text{favorable outcomes}}{\text{total outcomes}}#

#=\frac{3}{36}#

#=1/12#
