Mensa is an organization that allows people to join only
if their Stanford-Binet IQs are in the top 2% of the pop-
ulation. Assume the population mean of Stanford-Binet
IQs is 100, and the standard deviation is 15, and that
the population is normally distributed.
What is the probability that two randomly selected
people both have Stanford-Binet IQs which qualify
them for Mensa?
