Compute each of the following probabilities. Label each problem
clearly and show all your work. Use the numbers you computed in
earlier parts of the project based on the class data set.
Problem 1: Suppose all of the Skittles in the class data set
are combined into one large bowl and you are going to randomly
select one Skittle.
(a) What is the probability that you select a green Skittle? (4

is selected. Identify the correct statement.
a.
If many chips are selected then, in the long run, approximately
30% will be red.
b.
If ten chips are selected then three will definitely be red.
c.
If seven consecutive white chips are selected then...
