2. A company has three machines B1, B2, and B3 for making 1 k2 resistors. It has been observed that 80% of resistors produced by B1 are within 50 N of the nominal value. Machine B2 produces 90% of resistors within 50 Q of the nominal value. The percentage for machine B3 is 60%. Each hour, machine B1 produces 3000 resistors, B2 produces 4000 resistors, and B3 produces 3000 resistors. All of the resistors are mixed together at random in one bin and packed for shipment. What is the probability that the company ships a resistor that is within 50 N of the nominal value?
