When we divide this by the total probability of choosing A, E, I, O, or U, (which the book tells us is .385), then we get a probability of .208. • The probability of choosing an E is .13. When we divide this by the total probability of choosing A, E, I, O, or U, we get a probability of .338. • The probability of choosing an I is .065. Divided by .385, the probability of choosing an I is then .169. • The probability of choosing an O is .08. Divided by .385, the probability of choosing an O is, like the final probability of choosing an A, .208. • The probability of choosing a U is .03. Divided by .385, the probability of choosing a U is then .078. confidence rating #$&*: 2 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Given Solution: `aThe probabilities for A, E, I, O, U are: .08. .13, .065, .08, .03. The sum of these probabilities is .385 The probabilities of the letters given a vowel: .08 / .385 = .208 .13 / .385 = .338 .065 / .385 = .169 .08 / .385 = .208 .03 / .385 = .078 These probabilities total 1. ** &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Self-critique (if necessary): ------------------------------------------------ Self-critique Rating: " Self-critique (if necessary): ------------------------------------------------ Self-critique rating: " Self-critique (if necessary): ------------------------------------------------ Self-critique rating: #*&!
