The experimental probability of an event is defined as the ratio of the number of times the event occurs to the total number of trials or observations.
In this case, Paul observed a total of 24 + 5 + 1 = 30 boats, of which 5 were sailboats.
Therefore, the experimental probability that the next boat Paul sees will be a sailboat is:
Experimental probability = number of sailboats / total number of boats
Experimental probability = 5 / 30
Experimental probability = 1/6
So the experimental probability of seeing a sailboat next is 1/6 or approximately 0.167.
