Question

Pr(A|B)=Pr(B|A)

true or false?

Answer #1

This statement will only be true in the event that P(A) = P(B)

Since by Bayee's theorem we have that

P(A/B) = =P(B/A)

if P(A) = P(B)

However, like justin rising points out we have to consider the event that A and B are mutually exclusive that is the event that A B = 0.

Assuming this is the case, and that the events A and B both have probability measure larger than zero.

P(A/B) = = = =

So summing it up we have

P(A) = P(B) or P(A B) = 0

=> P(A/B) = P(B/A).

Which of the following statements is true concerning the
partnership representative (PR)? A. A PR is not necessary in a 12 -
person partnership B. The PR is designated on Form 1065 C. The PR
must be designated by the IRS D. The PR must be designated in the
partnership agreement

Suppose that A,B⊂S such that Pr[A|B]=3/7, Pr[A]=9/20 and
Pr[B′]=13/20. What is Pr[B|A′]?

Prove that Pr[A] ≤ min(1, q/p) when Pr[B|A] ≥ p > 0 and Pr[B]
≤ q

True or false:
Mark A, if true and B, if false

a) Pr{Z < 0.63}
b) Pr{Z ≥ −0.63}
c) Pr{−2.12 < Z < 2.12}
d) Pr{−2.12 < Z < 0.0}
e) Pr{−4.00 < Z < 0.0}
f) Pr{Z < −1.32 or Z > 1.32} (you want the probability
that Z is outside the range −1.32 to 1.32)
g) Pr{−1.32 < Z < 1.32}
h) Add (f) and (g). Are you surprised? Why or why not?
