Suppose that a fair, 6 sided die is rolled. Let
X
indicate the event that an even number is rolled (in other words,
X
= 1 if an even number is rolled and
X
= 0 otherwise). Let
Y
indicate the event that 1, 2, or 3 is rolled (in other words,
Y
= 1 if 1, 2, or 3 is rolled and
Y
= 0 otherwise). Find
P
(X
= 0,
Y
= 1).

a)
13

b)
56

c)
16

d)
12

e)
23

f) None of the above




Suppose p(x,y)=xy^2/30,
x

16

b)
56

c)
12
