Since there are 4 yellow marbles and 20 total marbles, the probability of selecting a yellow marble without replacement is 4/20 or 1/5. After selecting a yellow marble, there are now 19 marbles left, with 4 of them being purple. So, the probability of selecting a purple marble from the remaining 19 marbles is 4/19.
Therefore, the overall probability of selecting a yellow marble and then a purple marble is (1/5) * (4/19) = 4/95.
Therefore, the correct answer is Start Fraction 4 over 95 End Fraction.
Consider a jar that has 20 marbles. There are 4 red, 4 blue, 4 green, 4 yellow, and 4 purple marbles. What is the probability of selecting a yellow marble without replacing it and then selecting a purple marble?(1 point) Responses 39/95 Start Fraction 39 over 95 End Fraction 10/25 Start Fraction 10 over 25 End Fraction 4/95 Start Fraction 4 over 95 End Fraction 1/25
