Question

HELP I have 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.

Answer 1

the 1st one should be larger

Answer 2

140 divided by 5.10 ( or 5ft and 10in ) comes to 27
so 27 out of 140 are professional basketball players in the U.S part

Now the NBA is ( take that 350-450 subtract those 2, that gives you 100) 100 divided by 6.70 ( or 6ft and 7in ) that's 14 out of that 100 

not that this part matters but I always subtract my totals
27 - 14= 13
there are 13 more basketball players in the U.S part than the NBA part
