3. Suppose that a recent poll of American households about pet ownership found that for households with pets, 45% owned a dog, 34% owned a cat, and 10% owned a bird. Suppose that three households are selected randomly with replacement. Further suppose that ownership is mutually exclusive (for example, no dog owners also own birds, or no cat owners also own dogs, etc.). 4. What is the probability that all three randomly selected households own a dog? 5. What is the probability that none of the three randomly selected households own a dog? 6. What is the probability that at least one of the three randomly selected households owns a dog? 7. What is the probability that
