Best answer
Given: Total number of bulbs = 200 Number of defective bulbs = 16 (i) Let A be the event of getting a defective bulb Total number of defective bulbs = 16 So, P(getting defective bulbs) = P(A) = 16/200 = 2/25 (ii) Let B be the event of getting non-defective bulb So, P(getting non-defective bulb) = P(B) = 1 – P(A) = 1 – 2/25 = 23/25.
