-. A particular electronic device is known to contain only 10-, 22-, and 48-52 resistors, but these resistors may have 0.25-, 0.5-, or 1-W ratings, depending
on how purchases are made to minimize cost. Historically, it is found that the
probabilities of the 10-S2 resistors being 0.25, 0.5, or 1 W are 0.08, 0.10, and
0.01, respectively. For the 22-S2 resistors the similar probabilities are 0.20,
0.26, and 0.05. It is also historically found that the probabilities are 0.40,
0.51, and 0.09 that any resistors are 0.25, 0.50, and 1 W, respectively. What
are the probabilities that the 48-S2 resistors are (a) 0.25, (b) 0.50, and (c) 1 W?
