3. Which of the following options represents a uniform probability model? Select ALL that apply. \( \square \) A. Picking a letter from the letters in probability \( \square \) B. Rolling a cube painted with 3 blue faces and 3 red faces \( \square \) C. Picking a day of the weekend from the days of the week \( \square \) D. Picking a coin from a bag containing 5 dimes and 5 nickels \( \square \) E. Rolling two dice where the sum of the two numbers is even

A uniform probability model is one where all outcomes have an equal chance of occurring. Let's analyze each option to determine which ones represent a uniform probability model: A. Picking a letter from the letters in probability: This is not a uniform probability model because the probability of picking each letter is not equal. B. Rolling a cube painted with 3 blue faces and 3 red faces: This is a uniform probability model because each face of the cube has an equal chance of landing face up. C. Picking a day of the weekend from the days of the week: This is not a uniform probability model because the probability of picking a weekend day is not equal to the probability of picking a weekday. D. Picking a coin from a bag containing 5 dimes and 5 nickels: This is a uniform probability model because each coin has an equal chance of being picked. E. Rolling two dice where the sum of the two numbers is even: This is not a uniform probability model because the probability of getting an even sum is not equal to the probability of getting an odd sum. Therefore, the options that represent a uniform probability model are B and D.
