Question
In a group of five students one has a paid subscription to Netflix. If one student is selected from the five, what is the probability of selecting this student (round your answer to one decimal place)?
Solution
The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes.
In this case, the favorable outcome is selecting the student with the Netflix subscription, and there is only one such student. The total number of outcomes is the total number of students, which is five.
So, the probability (P) is calculated as follows:
P = Number of favorable outcomes / Total number of outcomes P = 1 / 5
To convert this to a decimal, you divide 1 by 5, which equals 0.2.
So, the probability of selecting the student with the Netflix subscription is 0.2 or 20%, when rounded to one decimal place.
