Q3) Machines A and B make components, which are then placed on a conveyor belt. Of those made by machine A, 93% are acceptable. Of those made by machine B, 95% are acceptable. Machine A makes 60% of the components and machine B makes the rest. Find the probability that a component selected at random from the conveyor belt is (a) made by machine A (b) made by machine A and acceptable (c) made by machine B and acceptable (d) made by machine B and unacceptable

EXPRESS IN 4 DECIMAL PLACES! A metallic wire is stretched from original length of 2 m to 4 m. If the original cross-sectional area is 3 square millimeters and original resistance is 9 ohms, determine the new resistance (in ohms) of the metallic wire. Assume the volume of the wire is preserved.
