Ihave no idea how to do this.

the average height of the 140 million u. s. males is 5 ft. and 10 in. some males from the u. s. become professional basketball players. the average height of the 350–450 professional basketball players in the nba (national basketball
association) is about 6 ft. and 7 in. which of the following probabilities should be larger? or would they be similar?
the probability that a u. s. male over 6 ft. 7 in tall is a professional basketball player
the probability that a professional basketball player is over 6 ft. tall

explain your reasoning.
