thank you
Question 3 (1 point) A machine making lightbulbs occasionally makes defective lightbulbs. The number of defective lightbulbs made in a day follows a Poisson distribution with rate 0.15. What is the probability that it makes at least 2 defective lightbulbs in a day? (Give your answer to 5 decimal places.) Your Answer: Answer Question 4 (1 point) There are three urns. The first contains 1 black balls and 4 white balls. The second contains 2 black balls and 3 white balls. The third contains 6 black balls and O white balls. You choose an urn uniformly at random and then choose a ball from that urn uniformly at random. What is the probability that you chose a black ball? Your Answer:
Question 5 (1 point) There are three urns. The first contains 5 black balls and 1 white balls. The second contains 2 black balls and 2 white balls. The third contains 7 black balls and O white balls. You choose an urn uniformly at random and then choose a ball from that urn uniformly at random. Given you chose a black ball, what is the probability it came from the first urn? Your Answer:
