#### Solution Preview

Hello and thank you for posting your question to Brainmass.

Say we have 6 balls, three of them blue, two are red and one is green.
What is the probability of selecting a blue ball? we have three blue balls out of a population of six balls, thus the probability of selecting a single blue ball is : The number of blue balls in the population (3) divided by the total population (6), so it is

3/6 = 1/2.

By the same token, the probability of selecting a ...
