The following game is played: First, imagine a fair three-sided die exists with sides 1, 2, and 3. It is equally likely for any of the three sides to land up. We'll call the number that lands up n. Next, a coin is flipped n times. The number of heads that come up we'll call z. Find the following: a) Create a joint probability mass function for r and n. b) Find P(x = 1/n = 2) c) Find P(x > 4/n = 3) d) Find P(z=1nn = 3) e) Find P(r2 2) f) Are x and n independent? Explain why or why not.

The following game is played:
First, imagine a fair three-sided die exists with sides 1, 2, and 3. It is equally likely for any of the three sides
to land up. We'll call the number that lands up n.
Next, a coin is flipped n times. The number of heads that come up we'll call z.
Find the following:
a) Create a joint probability mass function for 2 and n.
b) Find P(r = 1|n = 2)
c) Find P(x > 4n = 3)
d) Find P(x=1nn=3)
e) Find P(x > 2)
f) Are x and n independent? Explain why or why not.
