The probability of selecting a yellow marble is 4/20 or 1/5.
After selecting a yellow marble without replacing it, there would now be 19 marbles in the jar and only 3 purple marbles remaining. Therefore, the probability of selecting a purple marble is 3/19.
To find the probability of both events happening, we multiple the probabilities:
(1/5) x (3/19) = 3/95
Therefore, the probability of selecting a yellow marble and then a purple marble without replacing the first marble is 3/95.
