Please ask one question

Think about the answer, interact with the answerer. (which you may have done here)

Then

Put the next question in a DIFFERENT post

Thanks Dragon,

but

next time please put a link between the original and the new questions Dragan. (one on both ends)

Let team A have 5 members 2 of which are captains.

Let team B have 7 members 2 of which are captains.

Let team C have 8 members 2 of which are captains.

the probability of choosing team A then a captain from it then another captain from it is

                   \(\frac{1}{3}*\frac{2}{5}*\frac{1}{4}=\frac{1}{30}\)

Now do the same thing for team B and for Team C and then add all those probabilities together.

This is a teaching answer - please let guest asker finish it for him/herself.

What is the rest of it? 

5E+01    most likely means    5*10^1   =   50

3!*4!=6*24= 144

If it did not have integer coefficients the answer would be 0.

BUT

with integer coefficients I do not know ???

If I had time and inclination I would go watch some videos on Rational Root Theorum and maybe I could figure it out.

BUT

I'd really like someone to show my how to do it here.     

Any takers?

To NewMember

I'd like if if you 'had it' and I a appreciate you use of 'thanks' here ........  but so far I see evidence to the contrary.

You have voted answer 1 down AGAIN

You have voted yourself up saying 'got it'.

You have NOT thanked Heureka here for linking you to his answer.

AND

You have NOT thanked Heureka for his answer on the original thread.

Seems you know how to abuse people but you don't know much about common courtesy.

Good work EpicWater.

It is always good when you can solve it by yourself!   

1) One suggestion would be to make a new post of your own.

Ask if any users can help you with your adblocker problem.

2) Maybe also some you know in person, like a friend or relative, (not on the forum) might know more than you and might be able to help you.

3)  Here is one site that might help.  

OR maybe do your own search, you might find better help.

Like this is for internet explorer, maybe you need instructions for Google Chrome or some other browser.

EP just made a careless mistake, it is no big deal. 

It does not even detract from his answer since only the method is important.
