Answer:

The probability of picking a purple marble, and then, not replacing picking an orange marble is approximately 20%

Step-by-step explanation:

First we know that there are 20 marbles in the bag, so the probability of picking a purple marble is 11/20. If we take a purple marble out, there will only be 19 marbles remaining in the bag. So the probability of picking an orange marble would be 7/19. Now, all we need to do is multiply the 2 fractions, and we will get 77/380 which equals to which is approximately 20% .

Answer

The answer is 20%
