You randomly select an integer from 0 to 24 ​(inclusively)
and then randomly select an integer from 0 to 19 ​(inclusively).
What is the probability of selecting a 2 both​ times?
~~~~~~~~~~~~~~~ 

First time you select randomly from 25 integer numbers [0, 1, 2, 3, . . . , 23, 24].


Second time you select randomply from 20 integer numbers [0, 1, 2, 3, . . . ,18, 19].


Your second selection is INDEPENDENT from your first selection.


THEREFORE, the probability to get  " 2 "  both times is  %281%2F25%29%2A%281%2F20%29 = 1%2F500 = 0.002 = 0.2%.    ANSWER

Solved.
