When calculating probability, you are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a spinner would land on a part with an even number we should use the Probability Formula.
P=Favorable Outcomes/Possible Outcomes
Now, we can look at the spinner and find the number of possible outcomes.
There are 6 numbers on the spinner which is also the number of possible outcomes. To find favorable outcomes, we should calculate how many outcomes result in a spinner landing on an even part. An even number is any integer that is divisible exactly by 2, so we have to choose any parts with such numbers.
Out of these, there are 3 such outcomes which is also the number of favorable outcomes. Now we have enough information to calculate P(Even).
