QUESTION 1

Event A has probability 0.15, event B has probability 0.48. The probability of (A and B) is 0.08. What is Pr(A|B) (probability of A given B)?

QUESTION 2

Event A has probability 0.13, event B has probability 0.32. The probability of (A and B) is 0.09. What is Pr(B|A) (probability of B given A)?

QUESTION 3

Event A has probability 0.16, event B has probability 0.37. What must be Pr(A and B) in order for A and B to be independent?

QUESTION 4

Pr(A) = 0.32, Pr(B) = 0.47. If A and B are mutually exclusive, what is Pr(A|B) ?

QUESTION 5

Pr(A) = 0.32, Pr(B) = 0.38. Pr(A|B) = 0.48. What is Pr(A and B) ?

QUESTION 6

Pr(A) = 0.38, Pr(B) = 0.47. Pr(A|B) = 0.27. What is Pr(A or B) ?

Recall that 'or' is an inclusive or, meaning "one or the other or both".

QUESTION 7

Pr(A) = 0.37, Pr(B) = 0.43. Pr(A|B) = 0.33. What is Pr(~A and ~B) ? (Probability of not A and not B).

QUESTION 8

Pr(A) = 0.37, Pr(B) = 0.37. Pr(A|B) = 0.13. What is Pr(~A and B) (probability of not A, and B)?

QUESTION 9

You roll 2 standard six-sided dice. What is the probability that all rolls will come up less than or equar to 2?

Enter answer accurate to 4 decimal places.
