Calculate Vowel Probability: Calculate the probability of spinning a vowel three times consecutively. The spinner has 4 vowels (A, E, I, O) out of 6 possible outcomes (A, B, C, D, E, I, O). The probability of spinning a vowel once is 64 or 32.
Calculate Vowel Probability Consecutively: Since each spin is independent, the probability of spinning a vowel three times is (32)×(32)×(32)=278.
Calculate Number Cube Probability: Calculate the probability of rolling a number less than 3 on a number cube three times consecutively. Numbers less than 3 on a cube are 1 and 2, so the probability for one roll is 62 or 31.
Calculate Number Cube Probability Consecutively: Since each roll is independent, the probability of rolling a number less than 3 three times is (31)×(31)×(31)=271.
