Ok. So the probability that Shania arrives on time for school for day two is also 1/2, day three is 1/2. and four is one half, and day five is 1/2. Since the probability of all the events occuring is them multiplied together, you are looking for (1/2)^5. Then, you need to convert the resulting fraction into a percent.
