a spinner is divided into 11 equal sections numbered from 0 to 10. you spin the spinner once. what is P (not even)?
A. 3/5
B.1/2
C.5/11
D.6/11
1, 3, 5, 7, and 9 are the "not even" (odd) numbers
there appear to be five of them...out of 11
P(not even) = 5/11
ANSWER IS 6/11
To find the probability of not getting an even number on the spinner, we need to first determine the number of odd numbers on the spinner and then divide it by the total number of possible outcomes.
In this case, the odd numbers on the spinner are 1, 3, 5, 7, and 9. So there are 5 odd numbers.
Since the spinner is divided into 11 sections in total, there are 11 possible outcomes.
To find the probability, we divide the number of favorable outcomes (not even numbers) by the total number of possible outcomes.
So, the probability of not getting an even number on the spinner is 5/11.
Therefore, the correct answer is option C. 5/11.
