I need help with Annual Return, thanks!! Alice is a Star Trek fan, and in 2004 she bought a gold-
rimmed collector's plate with a painting of Mr. Spock on it
for $25. In 2019 she needed to downsize for a move so
she sold the plate on eBay for $49. What was her annual
return on the collector's plate? Write your answer as a
percentage.

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?
