psychological test

A psychological test identifies people as being one of eight types. For instance, Type 1 is “Rationalist” and applies to 15% of men and 8% of women. Type 2 is “Teacher” and applies to 12% of men and 14% of women. Each person fits one and only one type.

a. What is the probability that a randomly selected male is either a “Rationalist” or a “Teacher”?

b. What is the probability that a randomly selected female is not a “Teacher”?

c. Suppose that college roommates have a particularly hard time getting along with each other if they are both “Rationalists.” A college randomly assigns roommates of the same sex. What proportion of male roommate pairs will have this problem?

d. Refer to part (c). What proportion of female roommate pairs will have this problem?

e. Using your answers to parts (c) and (d) and assuming that half of college roommate pairs are male and half are female, what proportion of all roommate pairs will both be “Rationalists”?
