The probability of success will be 20%.

Explanation:

As long as nothing changes, the probability of success will always be 20% with each try.

For example, if you have a jar of 20 red marbles and 80 green marbles, all the same size and thoroughly mixed, the chance that you will randomly pull out a red marble will be 20%. If you return the red marble to the jar, and thoroughly mix the marbles, there will still be a 20% chance that you will randomly pull out a red marble.
