Hi, Stupid question. What are the odds of picking one outcome out of three, if you have two attempts and the one you pick is removed from the pool? First time should be 1 of 3, or 33% second is 1 of 2, 50%. How is the total calculated?

Why is it lower than the 33.3% odds in the first attempt? Shouldn't it be higher? Sorry, I am just really confused.

Chance of 2nd try is the chance of the desired number x still being there (2/3) times the chance of getting the number x out of the 2 remaining ones (1/2). This is ⅔•½=⅓
