4. A spinner is divided into 10 equal sections numbered from 1 to 10. You spin the spinner once. What is P(not even)?
Is the answer 5/11? If it is, explain how you got the answer, please..
To find the probability of selecting an outcome that is not even, we need to determine the number of favorable outcomes (not even numbers) and divide it by the total number of possible outcomes.
In this case, we have a spinner with 10 equal sections numbered from 1 to 10. Out of these numbers, the even numbers are 2, 4, 6, 8, and 10.
Since we want to find the probability of not getting an even number, we need to find the number of odd numbers on the spinner. These are 1, 3, 5, 7, and 9.
Therefore, the number of favorable outcomes is 5, and the total number of possible outcomes is 10.
To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes:
P(not even) = Number of favorable outcomes / Total number of possible outcomes
= 5 / 10
= 1 / 2
So the probability of not getting an even number when spinning the spinner once is 1/2, not 5/11.
