THE PROBABILITY OF PICKING AN ITEM (CARD, BALL, CHOCOLATE OR ANY ITEM)
Q = Probability of selecting green if you have 100 items = 20 red, 20 blue, 40 green, 10 yellow, and 10 orange, the probability of selecting a green one would be 40/100.
Probability of selecting the green on the first, 10th or 100th will also be the same = 40/100.
EXCEPTION = Only if the probability is with an exception or rule such as below:
Probability to draw two cards from a pack of 52, what is the probability of getting a queen first and kind second is 13/52*13/51.
Hence to conclude when its probability of picking an item without any condition it does not matter which attempt you pick, it will be the same
