Answer:
14/33
Step-by-step explanation:
Okay so first of all, we want to find the probability of picking that first purple marble. There are 8 purple marbles you can chose out of a possible 12 marbles, so the probability is 8/12, or 2/3.
Next, find the probability of finding the second purple marble. Since you took out one purple marble already, there are 7 purple marbles you could chose out of a possible 11 marbles, so the probability is 7/11.
To find out the probability of both of these events happening, you multiply these probabilities:
[tex]\frac{2}{3} * \frac{7}{11}\\\frac{2*7}{3*11} \\\frac{14}{33}[/tex]
