Do these situations involve Bernoulli trials? Explain.a. We roll 50 dice to find the distribution of spots on the faces.b. How likely is it that in a group of 120, the majority has type A blood, given that TypeA blood is found in 43% of the population?c. We deal 7 cards from a deck and get all hearts. How likely is that outcome?d. We wish to predict the outcome of a vote on the school budget, and poll 500 of the3000 likely voters to see how many favor the proposed budget.

7. Career education Surveys of recent high-school dropouts revealed that many of these students saw little connection between what they were studying in school and their future plans. To change this perception, researchers developed a program called CareerStart, in which teachers show students how the topics they learn about are used in specific careers. Seven of the 14 schools in Forsyth County, North Carolina, were selected at random to use CareerStart along with the district's standard curriculum. The other seven schools just followed the standard curriculum. Researchers followed both groups of students for several years, collecting data on students' attendance, behavior, standardized test scores, level of engagement in school, and whether or not the students graduated from high school. Results: Students at schools that used CareerStart typically did better in each of these areas. Explain why it was necessary to include a control of schools that didn't use the CareerStart program.³…
