Please help me solve this statistic problem (a floor function is a function that rounds down to the nearest integer)

Consider a discrete random variable Y with cdf denoted F(x) . Assume that O X 8 where x| denotes the floor function Given that E(Y) -51 /16 calculate the standard deviation of Y. (Hint: It may help to first solve for the pmf of Y.)
