Noah has a toy that requires 4 batteries. Noah buys batteries with a chance of lasting more than 2/3 hours, and he wants to estimate the probability that at least one of the 4 batteries in his toy will go dead before 15 hours are up. Noah wants to use a spinner with equal-sized sections to represent each battery’s chance of lasting more than 15 hours. He will use red sections to represent a battery that dies before 15 hours are up and green sections to represent batteries that last more than 15 hours. How many of each section should Noah have in his spinner? Explain.
