P 3 10 7 9 2 8 p 7 120 since we were ask to find the probability of chosing 1 red 1 black and 1red marble without replacement after each draw we can use the fundamental method in finding the probability.
Box with marbles in them you draw out three.
That means the box has to be full of red marbles if there were white ones too the sticker would have been on a correct box.
Three closed boxes have either white marbles black marbles or both and they are labeled white black and both.
You may reach into one of the boxes and pull out only one marble.
Which box should you remove a marble from to determine the contents of all three boxes.
One marble is drawn.
There are 3 red marbles and 7 black ma.
Three closed boxes have either white marbles black marbles or both and they are labeled white black and both.
Sampling from the box with replacement will return a black marble frac13 of the time.
You only need one.
Are the events red black and yellow mutually exclusive.
However you re told that each of the labels are wrong.
You may reach into one of the boxes and pull out only one marble.
You draw one marble from a box with a sticker red and white let s say its red.
In the three samples you draw if two are to be black the non black marble could be drawn first second or third three possibilities in total.
Which box should you remove a marble from to determine the contents of all three boxes.
