And then we have 3 green marbles let me draw those 3 so 1 2 3. And we write it as probability of event a and event b equals the probability of event a times the probability of event b given event a let s do the next example using only notation. A draw the tree diagram for the experiment. B the probability of getting.

Probability examples a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles what is the probability that you draw and replace marbles 3 times and you get no red marbles. 2 blue marbles so we have 1 blue marble 2 blue marbles.
