The probability of choosing a blue marble is 5 in 15 or 1 in 3. The probability of then choosing a green marble is 5 in 14. (One is missing) Multiply the two probabilities and you get 5 in 42.(P = 0.1190... about 12%).

The probability of drawing a white marble is .46
The answer depends on which letters are in the bag!
It is incalculable.

well the dimes account for about 1/4 of the amount so about 25%

A laundry bag contains 160 black socks and 300 red socks. 1940 black socks must be added so that the probability of choosing a black sock is 7 of 8.
If you reach into the bag, grasp, and withdraw your hand, the probability of pulling something out is about 100%.
Now the 2 bags contain a total of 6 dimes and 5 quarters, which is a total of 11 coins. Therefore, the probability of getting a quarter is (5/11) which is about 0.4545.... or 45.45% as the case may be. Hope this helps
