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.

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.
