A Company manufactures bulb. 4 percent of it are defective. A Supervisor selects 2 bulbs at random. What is the probability that atleast one of the bulb is not defective?
The Attempt at a Solution
probability of selecting atleast one non defective bulb = 1 - probability of selecting 2 defective bulbs
= 1 - C[4,2]/C[100,2]
IS IT RIGHT?
