Two number cubes are rolled. Each number cube has sides numbered 1 through 6.
What is the probability that the outcome of the roll is a sum that is a multiple of 6 or a sum that is a multiple of 4?
Number of sums that are Multiples of 6::
sum = 6:: 1/5;2/4;3/3;4/2;5/1------5
sum = 12:: 6/6---------------------1
----
Number of sums that are a multiple of 4::
sum = 4:: 1/3;2/2;3/1--------------3
sum = 8:: 2/6;3/5;4/4;5/3;6/2------5
sum = 12: 6/6----------------------1
-----
# of "success" sums = 5+1+3+5 = 14
----
Total # of random sums----------36
------------------------------------
Answer:: 14/36 = 7/18
