Evaluate the following

A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two dimensional 3 × 7 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey. Then it should create a report that includes the following information: I. Average amount of food eaten per day by the whole family of monkeys. II. The least amount of food eaten during the week by any one monkey. III. The greatest amount of food eaten during the week by any one monkey. Input Validation: Do not accept negative numbers for pounds of food eaten.
What is the probability that two female students will be selected at random, one after the other, to participate in a research project from a class of 7 male and 3 female students?
Write a program that will predict the size of a population of red ants. The program should ask the user for the starting number of red ants e.g. 2,000,000, their average daily population increase as a percentage of current population e.g., 5%, and the number of days they will multiply e.g. 10 days. Use a do while to display the size of the population for each day. Draw a flow chart and write down a pseudo code before attempting this number. Input Validation: Do not accept a number less than two for the starting size of the population. Do not accept a negative number for average daily population increase. Do not accept a number less than one for the number of days they will multiply.
Every cereal box has a gift inside, but you cannot tell from the outside what the gift is. The store manager assures you that 12 of the 57 boxes on the shelf have the secret decoder ring. The other 45 boxes on the shelf have a different gift inside. If you randomly select two boxes of cereal from the shelf to purchase, what is the probability that BOTH of them have the secret decoder ring?
