In our rental shop case, we know that on the busiest day we canexpect 150 rentals, which forms the number of independent events ortrials. We also know that, historically, 60% of our customers rentskis and 40% rent snowboards, which provides our probability. If wedecide that we only need to have 65 snowboards in stock, what isthe probability that we will run out of snowboard rentals on anyspecific day?
