Question

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?

	has a cat	does not have a cat
does not have a dog	15	2

Explanation:

Step1: Calculate total number of students

$5 + 7+15 + 2=29$

Step2: Calculate number of students with a cat

$5+15 = 20$

Step3: Calculate the probability

Probability = $\frac{\text{Number of students with a cat}}{\text{Total number of students}}=\frac{20}{29}$

Answer:

$\frac{20}{29}$
