Question 1142629: Three dice are rolled at once what is the probability of obtaining same face faces
1/36
1/2
1/6
1/72 Found 2 solutions by math_helper, Edwin McCravy:Answer by math_helper(2461) (Show Source):
Let's get the number of SUCCESSFUL ways:
There are only 6 successful ways they can come up:
All 1's, all 2's,..., all 6's.
Now let's get the number of POSSIBLE ways:
There are 6 possible ways the first die can come up
TIMES
6 possible ways the second die can come up
TIMES
6 possible ways the third die can come up.
So that's 6×6×6 = 6³ = 216 ways.
So the probability is 6 successful ways out of 216
possible ways, or 6 out of 216 or 6/216 which reduces
to 1/36.
