You are a DJ at a wedding. A playlist contains 10 pop songs and 20 country songs. You set the playlist to select songs at random. Once a song is played, the same song will not play again. Find the probability that the first two songs to play are both country songs. Express your first answer as a fraction in simplest form, and round your percent answer to the nearest tenth. The probability is , or about %.

The winners of a carnival game draw a ticket from a box to determine their prize. Each winner draws a ticket and places it back into the box before the next draw. Every winner has a 28% chance of getting a pencil pouch, a 56% chance of getting a backpack, and a 16% chance of getting a gumball.The game operator wants to simulate what could happen for the next ten winners.So for each winner, she generates a random whole number from 1 to 100.She lets 1 to 28 represent a winner getting a pencil pouch, 29 to 84 a backpack, and 85 to 100 a gumball.Here is the game operator's simulation.Winner 1 2 3 4 5 6 7 8 9 10Random number 46 71 66 72 32 55 7 59 4 28In the simulation, which prize did each winner get?(a) Winner 4: (b) Winner 9: (c) Winner 10:
