    Probabilities Logical Problem

    Hi, i would like to leave you here a logical problem related with probabilities, if you can help me i would appreciate a lot!.

    The problem:

    You have a box with 6 glasses (A,B,C,D,E,F), and you are asked to try to pick, lets say the glass B, and you have 3 chances of picking the right glass(you can pick a glass 3 times), without returning the glasses to the Box (that are the rules, and are stated before anything).

    My question is: Does make any diference, i mean probabilistically, if i just pick 3 glasses from the box or if i pick the glasses 1 by 1, i mean picking one, and if i loose, i pick another, then another???

    Thats my question, from my point of view i would say its make no difference, since its stated from the beginning that you are able to pick a glass 3 times.

    Would be different if i am able to pick only 1 glass, fail to pick the right glass, and THEN it is offered to me another chance to pick a glass, right??

    Thx in advance!! hope you can read this and answer me

    PD: Sry for my poor english, its not my lative languaje

    Whether you pick all of them at the same time or one by one it makes no difference in terms of probability
