In a medical study, patients are classified in 8 ways according to whether they have
blood type AB+, AB−, A+, A−, B+, B− , O+, or O−, and also according to whether their
blood pressure is low, normal, or high. Find the number of ways in which a patient can
be classified.

Find the value of σ x̅. Use the choices on no. 4 problem. Use this data: Consider the score examples illustrated, in which random samples of size 16 are obtained from N (25,9)
Two of the five (5) foreign automobiles from an overseas shipment have slight paint blemishes. If an
agency receives three (3) of these automobiles at random, list the elements of the sample space 𝑆 using
the letters B and N for “blemished” and “non-blemished”, respectively. For each sample point, assign a
value 𝑥 of the random variable 𝑋 representing the number of automobiles purchased by the agency with
paint blemishes. Hint: There are eight (8) elements in the sample space.

An overseas shipment of 5 foreign automobiles contains 2 that have slight paint
blemishes. If an agency receives 3 of these automobiles at random, find the
probability distribution of the random variable X representing the number of
automobiles with paint blemishes purchased by the agency. Find the mean
number of automobiles with paint blemishes. Also, calculate the variation.
