Historically, there is a 40% chance of having clear sunny skies in seattle in july. let's assume that each day is independent from any other day (although this is not really true under this assumption, if you will spend 18 days in seattle in july, what's the probability of having clear sunny skies on at least 13 of those days? (a) solve this exactly (b) solve this by approximating using a normal distribution. 8.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
