Suppose you spin a spinner with eight equal sectors numbered 1 to 8. What is the probability of spinning a 3 or an 8
There are two favorable outcomes (spinning a 3 or spinning an 8) out of eight possible outcomes (numbered 1 to 8). Therefore, the probability of spinning a 3 or an 8 is 2/8 or 1/4.
To determine the probability of spinning a 3 or an 8 on the spinner, follow these steps:
Step 1: Determine the total number of possible outcomes. Since the spinner has eight equal sectors numbered from 1 to 8, there are 8 possible outcomes.
Step 2: Determine the number of favorable outcomes. In this case, the favorable outcomes are spinning a 3 or an 8. There are two sectors that meet this condition, which are sector 3 and sector 8.
Step 3: Calculate the probability. Divide the number of favorable outcomes (2) by the total number of possible outcomes (8).
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 2 / 8
Simplify the fraction by dividing both the numerator and denominator by the greatest common divisor (2):
Probability = 1 / 4
Therefore, the probability of spinning a 3 or an 8 on the spinner is 1/4 or 0.25.
