Q1(A)A machine making lightbulbs occasionally makes defective lightbulbs. The number of defective lightbulbs made in a day follows a Poisson distribution with rate 0.22. What is the probability that it makes at least 2 defective lightbulbs in a day? (Give your answer to 5 significant figures.)

Q1(b)A machine making lightbulbs occasionally makes defective lightbulbs. The number of defective lightbulbs made in a day follows a Poisson distribution with rate 0.33. What is the probability that it makes at least 2 defective lightbulbs in a day? (Give your answer to 3 significant figures.)
