Question

Probability theory (Random Variables) At a motorcycle assembly plant, there are 50 employees. Each employee is required to complete the job on time and the work must pass through the examination. An employee may not be able to complete a job on time or the outcome of a job is not good or defective. At the end of the project, the Corporate Leader found that, 5 out of 50 employees were late in completing the work, 6 out of 50 employees produced defective products, and from 2 out of 50 late employees completed their work and produced defective products. How many chances Corporate Leaders get at random an employee who has a "poor performance rating"? [Work done is not timely and disabled]

Explanation / Answer

Answer to the question)

Total employees (n) = 50

Late (L) = 5

defective (D) = 6

Those who were late and had defective product (L and D) = 2

.

we need to find out the probability of those who got poor performance rating

poor performers are the once who were late and had defective products

thus P(L and D) = 2/50
