x*****g 发帖数: 108 | 1 Marie is getting married tomorrow, at an outdoor ceremony in the desert. In
recent years, it has rained only 5 days each year. Unfortunately, the
weatherman has predicted rain for tomorrow. When it actually rains, the
weatherman correctly forecasts rain 90% of the time. When it doesn't rain,
he incorrectly forecasts rain 10% of the time. What is the probability that
it will rain on the day of Marie's wedding?
