Deandre, a highway safety inspector, is concerned about the
potential for accidents caused by boulders that fall down a
sandstone cliff beside a main highway. As part of an accident
simulator, Deandre models the boulders' weights using a normal
distribution with a mean of 562 kg and a standard deviation of
100 kg.
Use a standard normal table or a calculator to find the

answer to two decimal places (for example 98.23%.
