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.

In a lottery, the top cash prize was $646 million, going to three lucky winners. Players pick four different numbers from 1 to 57 and one number from 1 to 47. A player wins a minimum award of $200 by correctly matching two numbers drawn from the white balls (1 through 57) and matching the number on the gold ball (1 through 47) What is the probability of winning the minimum award?
Jack has just been given a ten-question multiple choice quiz in history class. Each question has five answers, of which only one is correct. Since Jack has not attended class recently, he does not know any of the answers. Assuming Jack guesses randomly on all ten questions, find the probability that he will answer six or more of the questions correctly and avoid an F.
I would like to know how to find the correct answer.
