A draw the tree diagram for the experiment.
The following experiment is done a hundred times.
There are a total of 3 4 2 9 marbles in the box.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.
Therefore the probability of not drawing a red marble is the same as one minus the probability of drawing a red marble.
If a marble is drawn at random from the box what is the probability that it will be i white.
