question in a class of students, the following data table summarizes how many students have a brother or a sister. what is the probability that a student chosen randomly from the class has a brother? has a brother does not have a brother has a sister 10 3 does not have a sister 4 13

Answer

Explanation:

Step1: Calculate total students

Total students = 10 + 3+ 4+ 13 = 30

Step2: Calculate students with a brother

Students with a brother = 10 + 4 = 14

Step3: Calculate probability

Probability = $\frac{14}{30}=\frac{7}{15}$

Answer:

$\frac{7}{15}$
