Ilearned probability a few years ago, but i'm not quite sure how to solve this. can someone lend me some knowledge?

There are 12 marbles in total. 4 of them are white.

The probability of getting a white marble on the first try is 4/12 or 1/3.

The probability of getting a second white marble in a row? Since you already pulled out a white marble on the first attempt, there are now 3 white marbles and 11 marbles in total.  So the probability of getting a white marble at this point is 3/11.

Thus the probability of doing this back to back is 1/3 * 3/11 or 3/33 or 1/11.

The answer is B.

the answer will be 1/11

Step-by-step explanation:

5+2+4+1=12 and 12 two out or 12 of them will be pulled and if you think about it 8 out 4  white marbles

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
