Spinning a spinner that has 5 equal sections marked 1 through 5 and landing on an even number. What is the probability that the spinner lands on an even number?
To find the probability of landing on an even number when spinning a spinner with 5 equal sections marked 1 through 5, we need to determine the number of favorable outcomes (even numbers) and divide it by the total number of possible outcomes.
Step 1: Determine the number of favorable outcomes.
In this case, the favorable outcomes are the even numbers, which are 2 and 4.
Step 2: Determine the total number of possible outcomes.
The spinner has 5 equal sections, so there are 5 possible outcomes.
Step 3: Calculate the probability.
The probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Number of favorable outcomes = 2
Total number of possible outcomes = 5
Probability = Number of favorable outcomes / Total number of possible outcomes
= 2 / 5
= 0.4
= 40%
Therefore, the probability of landing on an even number is 40%.
To find the probability of landing on an even number, we need to determine the number of favorable outcomes (landing on an even number) and the total number of possible outcomes.
The favorable outcomes are the even numbers: 2 and 4. Therefore, there are 2 favorable outcomes.
The total number of possible outcomes is the total number of sections on the spinner, which is 5.
So, the probability of landing on an even number is given by:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Probability = 2/5
Hence, the probability of the spinner landing on an even number is 2/5 or 0.4 (which can also be expressed as 40%).
