You spin a spinner that has 12 equalized sections numbered 1 to 12. Find each probability.
P(odd or multiple of 5)
Find the probability :
P(multiple of 5 or odd)
Answer to Problem 5P
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 5 = 2 ={5,10}
Number of favorable outcomes that are odd numbers = 6 = {1,3,5,7,9,11}
Number of favorable outcomes that are odd and multiple of 5 = 1 = {3}
