A book is chosen randomly. Complete the steps to find the probability that the book is nonfiction given that it is hard-covered.
A veterinarian surveys her clients and finds that 32 percent of the households have dogs, 25 percent have cats, and 11 percent have both dogs and cats. Let event C be choosing a client who has cats and let event D be choosing a client who has dogs. Which statements are true? Check all that apply.P(C | D) = 0.78P(D | C) = 0.44P(C ∩ D) = 0.11P(C ∩ D) = P(D ∩ C)P(C | D) = P(D | C)
If events X and Y are independent, what must be true? Check all that apply.P(Y | X) = 0P(X | Y) = 0P(Y | X) = P(Y)P(Y | X) = P(X)P(X | Y) = P(Y)P(X | Y) = P(X)
P(paid) =
P(paid | game) =
The events “paid” and “game” are .
