Since the box contains 16 marbles, seven of them white, then the probability of drawing one white marble is 7/16. If you replace the marble and draw again, the probability of drawing another white marble is still 7/16. The net probability of drawing two white marbles, while replacing the first, is 49/256.

You have 12 marbles 8 are blue 4 are green what is probability one of each color is chosen on the first two draws?
If the two marbles are drawn without replacement, the probability is 16/33.
Suppose a jar contains 3 red marbles and 2 white marbles if a marble is drawn at random what is the probability it is red?
3/5 or .6
A bag contains 6 purple and 7 white marbles two marbles are drawn at random one marble is drawn and not replaced what is the probability that the fist marble is white and the second is purple?

A bag contains six blue marbles seven red marbles and four green marbles If four marbles are drawn randomly determine the probability that three are green?
It is 1248/57120 = 13/595 = 0.0218 approx.
A jar contains 11 white and 21 blue marbles a marble is drawn at random pnot blue express the probability as a fraction?
Probability of not blue is the probability of white. The probability of white is 11/(11+21) or 11/32.

There is a probability of 3 that it will be blue.
A bag contains 6 purple marbles and 7 white marbles Two marbles are drawn at random One marble is drawn and not replaced Then a second marble is drawn What is the probability that the first marble?
There are 13 marbles in total. The order is specified.P(1st is white and the 2ndis purple) = (7/13)(6/12) = (7/13)(1/2) = 7/26.

If a bag contains 4 black 6 green and 2 yellow marbles and one marble is randomly drawn what is the probability that it is not black?
There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.

It is (1/2)5 = 1/32
A bag contains 5 red marbles 3 blue marbles and 1 green marble. A randomly drawn marble is not blue.?
it would be red because the probability is 5/9
A jar contains 11 white and 21 blue marbles a marble is drawn at random pnot blue express the probability as a fraction?
Probability of not blue is the probability of white. The probability of white is 11/(11+21) or 11/32.
