Philips Electronics is experimenting with the manufacture of a new type of electric bulb that is very difficult to mass produce at an acceptable quality level. Every hour the Quality Control Manager (QCM) takes a random sample of 6 bulbs produced on the assembly line and tests them for their quality sequentially. Probability that any one bulb is defective is considered to be 0.12. The QCM wants to know the probability of finding 3, 4, or 5. What is the probability of finding 3, 4, or 5 defectives in a random sample of 6 electric bulbs?
