There were 3 chihuahuas at the dog park last Saturday, along with 9 other dogs. Considering this data, how many of the next 20 dogs to arrive at the park next Saturday should you expect to be chihuahuas?
chihuahuas
Based on the data provided, the ratio of chihuahuas to total dogs at the park last Saturday was 3 chihuahuas out of 12 total dogs (3 chihuahuas + 9 other dogs). Therefore, the probability of a dog being a chihuahua is 3/12, which simplifies to 1/4.
If we apply this probability to the next 20 dogs arriving at the park, we can expect approximately 1/4 of them to be chihuahuas. Therefore, we can expect around 5 of the next 20 dogs to be chihuahuas.
