You roll three fair dice. What is the probability that the product of the rolls is ten or greater?
Here are the possible outcomes :
We have 216 oucomes
I'll let you count all the ones whose products are 10 or greater.....
Your count / 216 = the probability
There are total 216 outcomes if we could calculate it manually, It is better to use online probability calculators like these:
It is better to use such online calculators so that we could save time also along with having the answer of the question. Technology has changed quite a lot over the past years that it is not difficult to get help from such resources on web. But with its facilities we cannot totally depend upon such tools, better approach is to solve such equations by hand and learning the concept of their calculations. But if we are to solve such questions for quiz or general Q&A then best thing is to use online tools.
