Madison is calculating the area of a composite figure. The figure is made up of a rectangle with a base of 5 and a height of 3 and a triangle with a base of 5 and a height of 2. She finds the area of the rectangle by multiplying 5 and 3 to get 15 square units. Then she finds the area of the triangle by multiplying 5 and 2, and then multiplying by 2 to get 20 square units. She adds the areas together to get 35 square units. Is Madison's answer correct? Why or why not?

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual?
