passive approach, S = sale, N = no sale.
Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A =
aggressive approach, Pa =
So, P(A) is the probability that an aggressive approach was used, and so on.
(a) Compute P(S), P(S | A), and P(S | Pa). (Enter your answers as fractions.)
P(S) =
Enter a fraction, integer, or exact decimal. Do not approximate.
P(S | A) =
P(S | Pa) =
sale and Pa =
(b) Are the events S
passive approach independent? Explain.
No. P(S) + P(S | Pa).
Yes. P(S) = P(S | Pa).
Yes. The two events can occur together.
No. The two events cannot occur together.
(c) Compute P(A and S) and P(Pa and S). (Enter your answers as fractions.)
P(A and S) =

P(Pa and S) =
(d) Compute P(N) and P(N | A). (Enter your answers as fractions.)
P(N)
P(N | A) =
(e) Are the events N = no sale and A aggressive approach independent? Explain.
Yes. The two events can occur together.
No. P(N) + P(N | A).
Yes. P(N) = P(N | A).
No. The two events cannot occur together.
(f) Compute P(A or S). (Enter your answer as a fraction.)
P(A or S) =
