A certain river floods every year. Suppose that the low-water mark is set at 1 and the high-water mark Y has distribution function Fy (y) = P(Y ≤ y) = 1 - - ₁ 1 ≤ y < 00. (a) Verify that Fy (y) is a cdf. (b) Find fy (y), the pdf of Y. (c) If the low-water mark is reset at 0 and we use a unit of measurement that is of that given previously, the high-water mark becomes Z= 10(Y-1). Find Fz (2).
