Complete parts (a) through (d) people to order fast food? A survey was conducted, but the sample sizes were not Gender Dinina Preference Dine inside Order inside to go Order at the Male Female 30 16 Total 76 46 50 drive-through Total 104 200 154 200 258 400 a. If a respondent is selected at random, what is the probability that he or she prefers to order at the drive through? (Round to three decimal places as needed.) b. If a respondent is selected at random, what is the probability that he or she is male and prefers to order at the drive through? (Round to three decimal places as needed.) c. If a respondent is selected at random, what is the probability that he or she is male or prefers to order at the drive through? (Round to three decimal places as needed.) d. Explain the difference in the results in (b) and (c) OA. O B. O C. O D. The probability in part (b) is a marginal probability, while the probability in part (c) is a joint probability. The joint event in part (c) includes the possibility that just one of the two attributes occurs The two attributes in part (b) are collectively exhaustive, while those in part (c) are not. The two attributes in part (b) are mutually exclusive, unlike those in part (c)
