A pet store has 12 puppies for sale: 4 are golden retrievers, 3 are poodles, and 5 are beagles. What is the probability that a randomly chosen puppy is either a poodle or a beagle?
- 1/4
- 5/12
- 2/3 (correct answer)
- 1/3
Explanation: The total number of puppies is 12. The number of poodles is 3, and the number of beagles is 5. The number of favorable outcomes (poodle or beagle) is 3 + 5 = 8. The probability is 8/12, which simplifies to 2/3 by dividing both the numerator and the denominator by 4.
