Forty families gathered for a fund-raising event. Suppose the individual contribution for each family is normally distributed with a meanand a standard deviation of $125 and $32, respectively. The organizers would call this event a success if the total contributions exceed$5.400. What is the probability that this fund-raising event is a success? (You may find it useful to reference the z table. Round finalanswer to 4 decimal places.)Probability0.0239
