Practice makes perfect
When calculating a probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability of a spinner landing on number 8 we will use the Probability Formula. P=Favorable Outcomes/Possible Outcomes Now we can look at the spinner and find the number of possible outcomes.
On the spinner there are six values. 1, 2, 3, 4, 5, 6 Therefore, the number of possible outcomes is 6. We can also see that the spinner does not contain the number 8. This means that, in this case, the number of favorable outcomes is 0. Now we have enough information to calculate P(8).
P=Favorable Outcomes/Possible Outcomes
P(8)=0/6

0/a=0

P(8)=0
The probability of a spinner landing on number 8 is 0.
