A spinner is divided into 12 equal sections numbered 1-12. What is the probability of landing on a section with a number that is less than 5?
To find the probability of landing on a section with a number less than 5, we need to determine the favorable outcomes (number less than 5) and the total possible outcomes (all 12 sections).
Favorable outcomes:
The numbers less than 5 on the spinner are 1, 2, 3, and 4. Thus, there are 4 favorable outcomes.
Total possible outcomes:
Since the spinner is divided into 12 equal sections numbered from 1 to 12, there are 12 total possible outcomes.
Probability:
The probability is calculated by dividing the number of favorable outcomes by the total possible outcomes.
Probability = favorable outcomes / total possible outcomes
In this case, the probability of landing on a section with a number less than 5 is 4/12, which simplifies to 1/3 or approximately 0.333.
4 of the 12 sections are less than 5, right?
