The first marble is not returned in the bag before drawing the second.

A bag contains 5 red marbles and 4 green marbles.

Well in succession without replacement is more interesting and means the first blind draw is 5 12 chance as there are 12 total and 5 are green and your second draw there are 11 total but now only 4 of them are. If a marble is selected at random what is the probability that is is not blue. A bag contains 9 red marbles 8 white marbles and 6 blue marbles. A bag contains 5 red marbles 4 blue marbles and 1 green marble.

One marble is drawn out randomly. 5 red marbles 6 blue marbles 3 green marbles 4 black marbles 2 yellow marbles a marble will. Answer by richwmiller 17219 show source. We are to find the probability of choosing a red marble then a green marble without replacement.

What is the reasonable prediction for the number of times a green or black. A bag contains five green marbles three blue marbles two red marbles and two yellow marbles. A bag contains 4 green marbles 6 red marbles 14 orange marbles 5 brown marbles and 8 blue marbles. We will assume that only two marbles are drawn from the bag and hence there are two cases.

In this bag with x 2 5 marbles total x 1 are red. You draw 4 marbles out at random without. What is the probability that neither marble is blue. The probability of choosing a red marble is given by.

Then a second marble is. After choosing the red marble 8 marbles left. The required probability is. A bag contains 5 red marbles and 4 green marbles 9 marbles in total.

Hence the probability of choosing a red marble then a green marble without replacement is. You choose a marble replace it and choose again. You have a bag which contains only red and green marbles. The probability of drawing a red marble from the original bag is equal to that.

Also x 3 marbles have a scratch on them. Total number of balls in the bag 5 4 9. A bag contains 5 red marbles 4 green marbles and 1 blue marble. The first marble is returned in the bag before drawing the second.

A bag contains 8 red marbles 4 white marbles and 5 blue marbles. Find p red and blue. A marble is chosen at random from the bag and not replaced. Given that a bag contains 5 red marbles and 4 green marbles.

A are the four different colour outcomes equally likely. B find the probability of drawing each colour marble i e p green p blue p red and p yellow c find the sum of their probabilities.
