I got this little thing from my math class… wondered if any of you wanted to have a go (all you MIT people will thing this is a joke 🙂 ) The problem is you have to figure out how many different possible license plates you could have (3 random numbers and 3 random letters)… Any of you got it?\>

well since there are 26 letters in the alphabet you do  
26_26_26  
and 10 numbers  
10_10_10  
you get 17576 and 1000  
so you do 17576\*1000 and you get  
17576000  
😉

PS! That’s just my logic… dunno if it really is that way 😏

haha I have no idea 🙂 Isn’t there a nifty formula involving the nCr and nPr? I haven’t touched probabilities in at least 4 or 5 years, and I never really learned it well enough either.

EDIT: Syko’s way sounds like it is right.

:cyclops:

hehee, I had 15 points (A+) in the probabilities test :love:  
hmm, it has been a while but I would say Syko is right.
