Answer:

Here is your answer

Step-by-step explanation:

(i) P (a carton has no defective bulb) = 400/700 = 4/7

(ii) P (defective bulbs from 2 to 6) = P (2 defective bulbs) + P (3 defective bulbs) + P (4 defective bulbs) + P (5 defective bulbs) + P (6 defective bulbs)

= 48/700 + 41/700 + 18/700 + 8/700 + 3/700 = 118/700 = 59/350

(iii) P (defective bulbs less than 4) = P (no defective bulb) + P (1 defective bulb) + P (2 defective bulbs) + P (3 defective bulbs)

= 400/700 + 180/700 + 48/700 + 41/700 = 669/700
