Suppose that the telephone calls coming into a certain switchboard obey a Poisson probability law at a rate of 16 calls per minute. If the switchboard can handle at most 24 calls per minute, what is the probability, using a normal approximation, that in 1 minute the switchboard will receive more calls than it can handle (assume all lines are clear).
