in a pet store, there are 6 puppies, 4 gerbils, and 7 parakeets. if a pet is chosen at random, what is the probability of choosing a puppy or a parakeet? 11/17 13/17 10/17 none of the above
Answer
Explanation:
Step1: Calculate total number of pets
$6 + 4+7=17$
Step2: Calculate number of favorable outcomes
Number of puppies + Number of parakeets = $6 + 7=13$
Step3: Calculate probability
Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{13}{17}$
Answer:
$\frac{13}{17}$
