a. Shawn used small cubes to build a bigger cube that was solid and was three cubes long on each side. He then painted all the facts of the new, large cube red. He dropped the newly painted cube and all the little cubes came apart. He noticed that some cubes had only one face painted, some had two faces painted, and so on. Describe the number of cubes with 0, 1, 2, 3, 4, 5, or 6 faces painted. Have each member of the group choose a different number of faces and then combine your data to see if it makes sense. Look for any patterns that occur.
b. What would the answers be if the large cube was four small cubes long on side?
c. Make a conjecture about how to count the cubes with different number of painted faces if the large cube were n small cubes long on a side.

A group of five applicants for a pair of identical jobs consists of three men and two women. The employer is to select two of the five applicants for the jobs. Let S denote the set of all possible outcomes for the employer's selection. Let A denote the subset of outcomes corresponding to the selection of two men and B the subset corresponding to the selection of at least one woman. List the outcomes in A, B, AUB, AN B, and An B.

A survey classified a large number of adults according to whether they were diag- nosed as needing eyeglasses to correct their reading vision and whether they use eyeglasses when reading. The proportions falling into the four resulting categories are given in the following table: Use Eyeglasses for Reading Needs glasses Yes No Yes 0.44 0.14 No 0.02 0.40 If a single adult is selected from the large group, find the probabilities of the events defined below. The adult (a) needs glasses. (b) needs glasses but does not use them. (c) uses glasses whether the glasses are needed or not.arrow_forward4.
