A city has a 20% chance of having a flood in any given decade. The table shows the results of a simulation using random numbers to find the experimental probability that there will
be a flood in the city in at least 1 of the next 5 decades. In the table below, 1 represents a
decade with a flood. The numbers 2 to 5 represents a decade without a flood.
