Question

Suppose that you are offered the following "deal." You roll a die. If you roll a six, you win $10. If you roll a four or five, you win $6. If you roll a one, two, or three, you pay $5.

Part (a)

What are you ultimately interested in here (the value of the roll or the money you win)?

the number rolled
the type of die
the number of times a six is rolled

the number of winnings
Part (b)

In words, define the Random Variable X.

the probability of rolling a four

the amount of money made by rolling a six

the number of winnings

the number of numbers that can be rolled

Part (c)
List the values that X may take on.

a.1, 2, 3, 4, 5, 6

b.4, 5, 6

c. $5, $6, $10

d.−$5, $6, $10
Part (d)

Construct a PDF. (Enter your answers for P(X = x) as fractions. Round your answers for x · P(X = x) to two decimal places.)

X
P(X = x)

x · P(X = x)

6

4 or 5

1, 2, or 3
Part (e)

Over the long run of playing this game, what are your expected average winnings per game? (Round your answer to two decimal places.)

=
Part (f)

Based on numerical values, should you take the deal?

Yes, you should take the deal because the expected value is positive.

No, you should not take the deal because the expected value is negative.
