Cruise ships of the Royal Viking line report that 80 percent of their rooms are occupied during September. For a cruise ship having 800 rooms, what is the probability that 665 or more are occupied in September?
The number of occupied cruise ship, denoted as X, is binomial random variable with n=800, p=0.8, denoted as X~Bin(800,0.8). From the properties of binomial random variable, the mean of X = ...
Calculation of probability is provided.
