Concept explainers
You spin a spinner that has 12 equalized sections numbered 1 to 12. Find each probability.
P(multiple of 5 or multiple of 2)
Find the probability :
P(multiple of 2 or multiple of 5)
Answer to Problem 10P
Explanation of Solution
Given:
You spin a spinner that has 12 equal-sized sections numbered 1 to 12.
Formula Used:
P(A or B) = P(A) + P(B) − P(A and B)
Calculation:
Total number of sections = 12
Number of favorable outcomes that are multiple of 2 = 6 ={2,4,6,8,10,12}
Number of favorable outcomes that are multiple of 5 = 2 = {5,10}
Number of favorable outcomes that are multiple of 5 and multiple of 2 = 1 = {10}
