A survey is taken among customers of a fast-food restaurant to determine preference for hamburger or chicken. Of 200 respondents selected, 75 were children and 125 were adults. 120 preferred hamburger and 80 preferred chickens. 55 of the children preferred hamburger and 20 preferred chickens. Set up a 2x2 contingency table using this information and answer the following questions:FoodAge Hamburger Chicken TotalChild 55 20 75Adult 65 60 125Total 120 80 200a) What is the probability that a randomly selected individual is an adult?b) What is the probability that a randomly selected individual is a child and prefers chicken?c) Given the person is a child, what is the probability that this child prefers a hamburger?d) Assume we know that a person has ordered chicken, what is the probability that this individual is an adult?

Priya bought two plants for a science experiment. When she brought them home, the first plant was 5cm tall and the second plant was 4cm. Since then, the first plant has grown 0.5 cm a week and the second plant has grown 0.75 cm a week.a. Which plant is taller at the end of 2 weeks? Explain your reasoning.b. Which plant is taller at the end of 10 weeks? Explain your reasoning.c. Priya represents this situation with the equation 5 + 0.5w = 4 + 0.75w, where w represents the end of week w. What does the solution to this equation, w = 4 represent in this situation? d. what does the solution to the inequality 5 + 0.5w > 4 + 0.75w represent in this situation?
