Human blood types are typically classied by the ABO blood group and the Rh blood group systems. Each individual has a blood type consisting of a combination of A, B, AB, or 0 from the ABO blood group and either + or from the Rh blood group (for example, blood type B. Blood types are an inherited trait and the proportion of each blood type will vary from region to region. Complete the contingency table for the probability of each blood type using the Venn diagram of the blood types for 1000 randomly sampled individuals from Israel. A pos B pos AB pos 0 pos A neg B neg AB neg W L \fO neg:Suppose the general manager of a company is asked to run a report to determine the educational background of employees at his company by age. The table displays the required information. Complete the table by calculating each marginal distribution for age and for education. The notation P(category) represents the marginal percentage for that category. Give your answer as a percentage, rounded to the nearest whole number.

However, when she asks for volunteers, 13 of her sisters are willing to help. Not wanting to play favorites, Kim decides to randomly select her five committee members from the 13 volunteers. How many different committees of five members are possible using this method?This Venn diagram shows the makeup of attendees at a college social event sponsored by the French Club. The event is open to all students. There are 35 students at the party who are fluent in Attendees at French Club party French. There are 50 students at the party who are fluent in English. There are 130 students at the party. Use the Venn diagram and given information to find the probability that a student selected at random is fluent in both French and English. Assume the chance of being selected is the same for each student. Express your answer as a percentage rounded to one decimal place. 28 13 Fluent English Fluent French speakers speakers Probability =Suppose a weather forecast reports that the probability of snow this week is 0.35. The forecast states that if it snows this week, the probability that it snows next week is 0.42. If it does not snow this week, the probability that it snows next week is 0.25.
