y<0 (1 1 point) Let F(x) = { 1 - = -e 504 y≥0 be the cumulative probability distribution function (CDF) for the random variable Y => the size (square footage) of a house with respect to the number of toilets. Let X be the number of toilets in the houses with respect to the size (square footage). a) Give the probability distribution function (PDF) for the random variable X. f(x)= f(x)= ;x? ;X ? b) If Y describes the size (square footage) of a house with respect to the number of toilets. How many toilets do you expect in houses with 2049 square feet? (use at least four digits after the decimal if rounding...) c) Plot the pdf of the number of toilets per 2049 square feet then select the graph below that looks closest to correct!
