Question

A basket contains 3 green and 2 yellow balls. One ball will be selected at

random and then not replaced. Then a second ball will be randomly selected

from the basket. G= # of green balls observed during the experiment.

16a) Draw a tree diagram with probabilities written on the branches. At the end of

each branch, identify each outcome of the Sample Space and its probability.

16b) Write the pmf (probability mass function) of in column format, identifying its

possible values and the probabilities of each value. (See the next problem for an

example of what a pmf in column format looks like.)
