10% of the bulbs produced in a factory are of red colour and 2% are red and defective. If one bulb is picked at random, determine the probability of its being defective if it red.

10% of the bulbs produced in a factory are red colour and 2% are red and defective. If one bulb is picked up at random, determine the probability of its being defective if it is red.

10% of the bulbs produced in a factory are of red colour and 2% are red and defective. If one bulb is picked up at random, then determine the probability of its being defective, if it is red.

In a bulb factory, machines A, B and C manufacture 25%, 35% and 40% bulbs respectively. Out of thse bulbs 5%, 4% and 2% of the bulbs produced respectively by A, B and C are found to be defective. A bulb is picked up at random from the total production and found to be defective. Find the probability that this bulb was produced by the machine B.

Three machinesE1, E2 and E3 in a certain factory producing electric bulbs, produce 50%, 25% and 25% respectively, of the total daily output of electric bulbs. It is known that 4% of the bulbs produced by each of machines E1 and E2 are defective and that 5% of those produced by machine E3are defective. If one bulb is picked up at random from a day’s production, calculate the probability that it is defective.

Three machines E 1, E 2, and E 3, in a certain factory producing electric bulbs, produce 50%, 25% and 25 % respectively, of the total daily output of electric bulbs. It is known that 4% of the bulbs produced by each of machines E 1, and E 2, are defective and that 5% of those produced by machine E 3, are defective. If one bulb is picked up at random from a day's production, then calculate the probability that it is defective.

In a bulb factory, machines A, B and C manufacture 60%, 30% and 10% bulbs, respectively. 1%, 2% and 3% of the bulbs produced, respectively by A, B and Care found to be defective. A bulb is picked up at random from the total production and found to be defective. Find the probability that this bulb was produced by machine A.
