for a certain class, the following data table compares how many students have a cat or a dog. what is the probability that a student chosen randomly from the class has a cat?\n| |has a cat|does not have a cat|\n|--|--|--|\n|has a dog|7|9|\n|does not have a dog|2|11|

Answer

Answer:

$\frac{9}{29}$

Explanation:

Step1: Calculate total students

$7 + 9+2 + 11=29$

Step2: Calculate students with a cat

$7 + 2=9$

Step3: Calculate probability

Probability = $\frac{\text{Students with a cat}}{\text{Total students}}=\frac{9}{29}$
