A spinner is divided into 8 equal parts. They are numbered 1-7 and the 8th has a star. What is the probability of it landing on the star?
prob(star) = 1/8
To find the probability of landing on the star, we need to determine the number of favorable outcomes (landing on the star) and the total number of possible outcomes (all the numbers on the spinner).
In this case,
- The number of possible outcomes is 8 since there are 8 equal parts on the spinner.
- The number of favorable outcomes is 1 since only one of the parts has a star.
So, the probability of landing on the star is the number of favorable outcomes divided by the total number of possible outcomes:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 1 / 8
Therefore, the probability of the spinner landing on the star is 1/8.
