There is a nice table of the standard normal distribution at Public Domain Normal Distribution Table, essentially the table you will see in any text book, however it's not really of much use here!

You appear to have calculated the "standard z scores" but "180" isso muchhigher than the mean of 40, as you say, almost 5 standard distributions above the mean, that it does not show up on the table. The table only goes up to z= 3.09. However, just below it on the same page is a more accurate table of "Far Right Tail Probabilities". That's what you need here. It does not give exactly your z-values but z= 4.6 gives P= 0.000002112 and z= 5.5 gives "1.899 E-8" or P= 0.00000001899. Subtract those to get the probability that the results will be in that interval. Obviously, because the interval is so far from the mean, the probability will be very, very low!
