A spinner is divdided into 10 equal sectors and numbered 1 through 10. Find the probability as a fraction, a decimal and a percent for P(composite numbers.
You spin the spinner shown two times. Each section of the spinner is the same size. Use this information to answer the question, giving a probability as a percent and rounding to the nearest tenth of a percent when necessary
What is the probability that the spinner stops on 4 first and 5 second?
P(4 ∩ 5) =
The probability of getting an odd number is 5/10 using a game spinner. The denominator of that probability is:
Bob
To find the probability of landing on a composite number when spinning the spinner, we first need to determine how many composite numbers are there in the given set of numbers. In this case, we have the numbers 1 through 10.
A composite number is any positive integer greater than 1 that is divisible by more than just 1 and itself. Looking at the given set, the composite numbers are 4, 6, 8, 9, and 10. These numbers can be divided by numbers other than 1 and themselves.
Now, we can determine the probability.
Step 1: Count the number of favorable outcomes.
In this case, the favorable outcomes are the composite numbers, which we have listed as 4, 6, 8, 9, and 10. So, we have 5 favorable outcomes.
Step 2: Count the total number of possible outcomes.
The total number of possible outcomes is the total number of sectors on the spinner, which in this case is 10.
Step 3: Calculate the probability.
The probability is the ratio of the number of favorable outcomes to the total number of possible outcomes.
Probability = Number of favorable outcomes / Total number of possible outcomes
Substituting the values:
Probability = 5 / 10
Simplifying the fraction, we have:
Probability = 1/2
So, the probability of landing on a composite number is 1/2.
To express this probability as a decimal, we can divide the numerator by the denominator:
Probability = 1/2 = 0.5
Finally, to express the probability as a percentage, we can multiply the decimal by 100:
Probability = 0.5 * 100 = 50%
Therefore, the probability of landing on a composite number is 1/2, 0.5, or 50%.
