Q3 (8 points) Q3. 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.
