Question

In a class of students, the following data table summarizes how many students play an instrument or a sport. What is the probability that a student chosen randomly from the class does not play a sport?

Answer 1

Answer:

10%

Step-by-step explanation:

First add all the students up together, = 30

out of those 30 students, only 3 with not play a sport, 30/3 = 10%

Answer 2

Using the probability concept, it is found that there is a 0.5 = 50% probability that a student chosen randomly from the class does not play a sport.

• A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem:

• In total, there are 8 + 7 + 3 + 12 = 30 students.

• Of this total, 3 + 12 = 15 do not play a sport.

Hence:

$p = \frac{D}{T} = \frac{15}{30} = 0.5$

0.5 = 50% probability that a student chosen randomly from the class does not play a sport.
