[rajemessage]

Dear All,

There are three numbers they can have two status "a" or "b".

I have to chose three number(1,2,3) , they will be in this order only.

Hello and welcome to MHB! :D

I have moved this thread because while it may be given in a university course, it is the type of problem you would find in an introductory course in statistics.

Now, you want to apply the fundamental counting principle. The number of combinations here will be the product of each numbers possible states...what would that be?

if possible please send me some links , with which i can formulate big numbers.yours sinclerely

That's okay, the problem is still worked in the same way, you will just have a different factor representing the number of states for "1." You want the number of states for "1" times the number of states for "2" times the number of states for "3"...what will this product be?

As for a site that will let you formulate numbers large and small, I recommend:

Wolfram|Alpha: Computational Knowledge Engine
