Using the scatter diagram given below, estimate the amount of downtime you would expect for an operation in this area if the operation has to be ceased if the probability that a maximum wave height of 7m is exceeded in a 40 minute duration is greater than 0.01. (use a spreadsheet program for this question as it will take too long to calculate by hand)

Calculate the probability of a 7m wave being exceeded in a 40 minute duration of each sea state and identify the sea states in which this is greater than 0.01.
