What is the theoretical probability of rolling a sum of 6 on one roll of two standard number cubes?

1 Answer

#5/36 #

Explanation:

There are #36# possible outcomes in rolling two six-sided cubes.

Of those #36# possibilities, five of them result in a sum of #6#.

#1+5:" " 2+4: " "3+3: " "4+2: " "5+1#

(#1+5# is different from #5+1" "# use two different colors of dice such as black and white to make this obvious)

#5# = the number of possibilities of getting a six.
#36# = the total number of possibilities (# 6 xx 6 = 36#

So the probability is #5/36 #
