q 28.) margaret asked her classmates how many pets they own. the responses are recorded in the table. find the probability that a classmate owns 1 or more pets. express your answer as a fraction.\n| number of pets | response |\n| ---- | ---- |\n| none | 7 |\n| 1 - 2 | 11 |\n| 3 or more | 5 |
Answer
Explanation:
Step1: Calculate total number of responses
Add up all the response - values: $5 + 11+7=23$.
Step2: Calculate number of students with 1 or more pets
Add the number of students with 1 - 2 pets and 3 or more pets: $11 + 5=16$.
Step3: Calculate the probability
The probability $P$ is the number of favorable outcomes (students with 1 or more pets) divided by the total number of outcomes (total students surveyed). So $P=\frac{16}{23}$.
Answer:
$\frac{16}{23}$
