Suppose S = {p, q, r, s, t, u} and A = {p, q, s, t} and B = {r,
s, t, u} are events.
x p q r s t u
p(x) 0.15 0.25 0.2 0.15 0.1
(a) Determine what must be p(s).
(b) Find p(A), p(B) and p(A∩B).
(c) Determine whether A and B are independent. Explain.
(d) Arer A and B mutually exclusive? Explain.
(e) Does this table represent a probability istribution of any
random variable? Explain.
