answer of word problem

@ myopenmath.com According to Masterfoods, the company that manufactures M&M's, 12% of peanut M&M's are brown, 15% are yellow, 12% are red, 23% are blue, 23% are orange and 15% are green. You randomly select six peanut M&M's from an extra-large bag of the candies. (Round all probabilities below to four decimal places: your answer should look like 0.1234, not 0.1234444 or 12.34%.) Compute the probability that exactly two of the six M&M's are red: 0.1295 ~/ (5' Compute the probability that two or three of the six M&M's are red: 0.1531 J 0" Compute the probability that at most two of the six M&M's are red: 0.1531 I Compute the probability that at least two of the six M&M's are red: 0.1556 ~/ 0" If you repeatedly select random samples of six peanut M&M's, on average how many do you expect to be red? 0.72 ~/ 0\" M&M's With what standard deviation? 0.7960 ~/ (5" M&M's Question Help: 8 Message instructor Submit Question Done 6 myopenmath.com AA (3 Chapters 5.1 - 5.2 Homework Score: 13.3/17 13/17 answered Progress saved Done (3) wlc. 0 Question 17 V l3 0/1 pt '0 3 8 99 G) Details United Airlines' flights from Denver to Seattle are on time 90 % of the time.

Consider 14 randomly selected people. a) State the random variable. 0 Select an answer b) List the given numbers with correct symbols. ?0 =14 ? 0 =0.12 c) Explain why this is a binomial experiment. Check all that apply. There are a fixed number of people, 14 There are only two outcomes for each person p = 12% remains constant from one randomly selected person to another Whether or not one randomly selected person is left- handed will not affect whether or not another randomly selected person is left-handed Whether or not one randomly selected person is left- handed will affect whether or not another randomly selected person is left-handed There is not a fixed number of people There are more than two outcomes for each person Find the probability, to 4 decimal places: It is possible when rounded that a probability is 0.0000
