# Math Help - probability

1. ## probability

In a probability experiment that records the sum of the numbers on the upper faces of the dice after they become stationary, the outcome with the greatest probability is...

2. ## Re: probability

Depends how many dice are being tossed. For two dice the most common result is 7.

How many dice are thrown?

4. ## Re: probability

It does not say

Then it's impossible to answer. The problem as you wrote it refers to "the dice" as if referring to some dice already discussed, perhaps in a previous question - are you sure there is no clue as to how many dice are involved?

6. ## Re: probability

1. Six

2. Seven

3. Eight

4. None of the above.

would you put none of the above?

7. ## Re: probability

Have a look at this web page.
The coefficients tell us the number of way we can get the various sums when four dice are used. For example the term $146x^{14}$ tells us there are 146 ways to throw a fourteen.

You can change the power 4 in $\left( {\sum\limits_{k = }^6 {x^k } } \right)^4$ to find out the numbers for any number of dice.

8. ## Re: probability

so would you just say None of the above? or 7?

Go to that webpage. Change 4 to 2. Click the $\boxed{=}$
Look for the largest coefficient.
