If I take two AA batteries out of my flash, and two more just like them from another place and mix them up, and then charge them, what are the odds of putting the same two back in the flash?
Wouldn't there be an exponential factor?If I take two AA batteries out of my flash, and two more just like them from another place and mix them up, and then charge them, what are the odds of putting the same two back in the flash?
Just a guess, 1 in 8. I am NOT doing this right now.

But what if the same two are picked together? either with the first two picks, the second two picks, the second and third pick, or the 3rd and 4th pick?Assuming random draws, 1 in 6.
The first battery you "draw" has a 2 in 4 chance of being one of the original batteries.
If you succeed in that, the second battery has a 1 in 3 chance of being the other original battery.
1/2 * 1/3 = 1/6
I drew it. But since A+B = B+A, does that factor into it?Wouldn't there be an exponential factor?If I take two AA batteries out of my flash, and two more just like them from another place and mix them up, and then charge them, what are the odds of putting the same two back in the flash?

You wanna figure it out? Write out a b c d, put together every possible combination and see how many = A+B together.
A+B= 1st 2 batteries.

Yeah, I should have realized that. Why keep picking once I have two? I must really be a rube like you say!But what if the same two are picked together? either with the first two picks, the second two picks, the second and third pick, or the 3rd and 4th pick?
The first and a second picks are all that matter, so they're the only ones used to calculate the odds.

Well, what's the answer, then?SNOEI vote we believe Mamooth.
