Question 1118701: An ordinary (fair) die is a cube with the numbers through on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events:
EventA : The sum is greater than .
EventB : The sum is an even number.

You can put this solution on YOUR website! An ordinary (fair) die is a cube with the numbers through on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events:
EventA : The sum is greater than .
Note:: EventA is not fully defined.
------------------------------------------
EventB : The sum is an even number.
Procedure::
Sketch a 6 by 6 square
Label the rows 1 to 6 ; Label the columns 1 to 6.
----
Fill in each of the 6 rows with the sum of row and column labels.
Example
Your 1st row:: 2,3,4,5,6,7
Your 2nd row:: 3,4,5,6,7,8
etc
Answer: (# of entries that are even)/(36)
