Factories a and b produce computers. factory a produces 4 times as many computers as factory b. the probability that an item produced by factory a is defective is 0.034 and the probability that an item produced by factory b is defective is 0.034. a computer is selected at random and it is found to be defective. what is the probability it came from factory a?

0.762

Step-by-step explanation:

We are given that

Factory A produces  4 times as many computers as factory B

Let be the event denotes computers produced by factory by A and factory by B.

Let

Then

Sum of all probabilities=1

Hence,

Let A denotes the event that an item is defective.

We have to calculate

Hence, the probability that the item produced by factory A and it is found to be defective=0.762

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
