8 sets of twins are entered in a competition. If 8
individuals are chosen at random, what is the probability none of
the chosen individuals are siblings?
Six sets of identical twins were randomly selected from a
population of identical twins. Note that identical twins are
genetically the “same” person. One child was taken at random from
each pair to form an experimental group and this group participated
in a program designed to promote creative thinking. The other child
was placed in a control group where no training was provided. At
the end of the program, each group was given a creative
problem-solving test with the results...

Twelve sets of identical twins were enrolled in a study to
measure the effect of home environment on certain social attitudes.
One twin in each set was randomly assigned to a foster environment
or a home environment. The twin assigned to the foster environment
went to live with a low income family on state welfare for a period
of 1 year. At the end of the year, an attitude survey was
administered.
Their results follow.

An urn has 8 red and 12 blue balls. Suppose that balls are
chosen at random and removed from the
urn, with the process stopping when all the red balls have been
removed. Let X be the number of balls
that have been removed when the process stops.
a. Find P(X = 14)
b. Find the probability that a specifed blue ball remains in the
urn.
c. Find E[X]
Perfect Competition (15)
1. What is unique about
perfect competition as a market structure that sets it apart from
the other three market structures we cover in this course? How does
it affect the diagrams that we use to analyze firm behavior?
