She has a 70% chance of rolling a four. She is playing a game with a friend and knows that if she rolls a four on three or more of her next five rolls she will lose the game. She wants to determine the probability that she rolls a four on three of her next five rolls. Loretta sets up her simulation using a table of random digits between 0 and 9. She let 0-6 represent rolling a four and 7-9 represent not rolling a four. She selects five digits. She preforms the simulation 18 times and records her results in the table. What is the probability that Loretta rolls a four on 3 of 5 rolls? A) 1/18 B) 1/6 C) 5/6 D) 17/18
