A police department reports that the probabilities that 0, 1, 2, and 3 burglaries will be reported in a given day are 0.50, 0.38, 0.10, and 0.02, respectively. Find the standard deviation for the probability distribution. Round answer to the nearest hundredth.

those can not be the answers....just compare with this one...very slit diffrent but the answer should near or close to0.2....
