forty families gathered for a fund-raising event. suppose the individual contribution for each family is normally distributed with a mean and a standard deviation of $115 and $35, respectively. the organizers would call this event a success if the total contributions exceed $5,000. what is the probability that this fund-raising event is a success? (you may find it useful to reference the z table. round final answer to 4 decimal places.)
