(c)

Show that your probability distribution satisfies the required conditions for a valid discrete probability distribution.

We have that

f(x) ? = ≤ ≥ 0

for

x = 1, 2, 3, 4

and

f(x) =

so the probability distribution satisfies the required conditions for a valid discrete probability distribution.
