You can put this solution on YOUR website! Consider the experiment of rolling two dice?
Sketch a 6 by 6 matrix.
Label the rows 1,2,3,4,5,6
Label the columns 1,2,3,4,5,6
-----
Fill the inner squares with the row/column sums
---------------------------------
What is the probability of obtaining a sum of three?:: 2/36 = 1/18
-----------------------------
What is the probability of obtaining a sum of four or less?:: 3/36 = 1/12
-----------------------------
What is the probability of obtaining a sum of eleven or more?:: 3/36 = 1/12
