A man wants to adopt a puppy from an animal shelter. At the shelter, he finds eight puppies that he likes, a male and female puppy from each of the four breeds of bloodhound, briard, chihuahua, and puli. The puppies are each so cute that he cannot make up his mind, so he decides to pick the dog randomly. Find the probability that the man chooses a male puppy. The probability of choosing a male puppy is . (Type a simplified fraction.)

To find the probability of choosing a male puppy from the eight available puppies, we first count the total number of puppies, which is 8 (4 breeds with 1 male and 1 female each). Among these, there are 4 male puppies (1 from each breed). Therefore, the probability of choosing a male puppy is the number of male puppies divided by the total number of puppies: Probability (choosing a male puppy) = Number of male puppies / Total number of puppies = 4 / 8 = 1 / 2. So, the probability of choosing a male puppy is **1/2**.
