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?
