Based on a survey, assume that 42% of consumers are comfortable having drones deliver their purchases. Suppose we want to find the probability that when six consumers are randomly selected, exactly two of them are comfortable with the drones. What is wrong with using the multiplication rule to find the probability of getting two consumers comfortable with drones followed by four consumers not comfortable, as in this calculation: (0.42 )(0.42 )(0.58 )(0.58 )(0.58 )(0.58 )equals0.0200?

Jamie and Stella are saving money to sign up for a school trip to Washington, D.C. In order to sign up for the trip, they must pay $600 upfront. Jamie earns his money by washing cars for $25 each. Stella earns her money by making pecan pies for $15 each. Jamie earns more money than Stella does because Stella only has enough supplies to make 40 pies. let x represent the number of cars Jamie washes. Let y represent the number of pies Stella makes. Part 1: Write a constraint (an inequality) to represent how much money Jamie needs for his trip. Part 2: Write a constraint (an inequality) to represent how much money Stella needs for her trip. Part 3: Write a constraint (an inequality) to represent the limitations of Stella's supplies. Part 4: Can Stella afford to sign up for the trip with the money she earns? Explain your answer and show any work that might support your answer.
