In a village, one bus arrives a day. The probability of rain is 0.27. If it rains, the probability of a bus being late is 0.39. If it does not rain, the probability of a bus being late is 0.15. Work out the number of days the bus will be late on average over a period of 71 days. (Give your answer in 2 d.p)

V. Explain how the complement can be used to find the probability of getting at least one item of a particular type. Choose the correct answer below. OA. The complement of "at least one" is "none." So, the probability of getting at least one item is equal to P(none of the items)- 1. O B. The complement of "at least one" is "all." So, the probability of getting at least one item is equal to P(all items) - 1. OC. The complement of "at least one" is "all." So, the probability of getting at least one item is equal to 1-P(all items). O D. The complement of "at least one" is "none." So, the probability of getting at least one item is equal to 1-P(none of the items). OL LL Next OL 10:50 AM 54°F Sunny 120Z/E2/LL F8 PrtSc F10 F11 F12 9. H. K. N. M.
