Title: got a quick math(?) question.
Post by: Jhanzo on January 28, 2016, 10:52:41 PM
first off. sorry if this sounds stupid.  :P

say I have to choose between three options with coin flipping, but can only flip the coin 2 times. first flip between option #1 (heads) and #2 (tails) and the second one between #3 (tails) and whichever option that was picked in the first flip (heads).
which option gets a better chance of getting picked?

The question is not really math, it is more statistics.

I think the problem is that you have not explained the problem you want to solve well enough.

The setup is a little unclear, are you flipping the coin 2 times.
I assume you have to the option before the flip.

First flip is fairly simple (if I have understood it correct), you can pick heads or tail.

Then is it unclear:

second one between #3 (tails) and whichever option that was picked in the first flip (heads).

You need to elaborate this....... ... ....

I thought it was clear enough...

if the result is tails, I choose option #3. if the result is heads, I choose the option that got picked on the first flip.

if I flip the coin twice and the result is HT, I'll choose option #3
if it's HH, I'll choose option #1
if it's TH, I'll choose option #2
if it's TT, I'll choose option #3

.............hey... I just got the answer.  ;D

problem solved! lol that was easy. I'm feeling dumb now.

Good to hear.

I still don't identify the statistical problem. Usually do you want to calculate the probability for different outcomes. Perhaps this is more of a logical problem... ? ...

May be its a logical question. but really I am poor in math lol.

yes true brother. Really can't make it. The brain is not working though.
