Basic Probability Worksheet | Grade1to6 - Free Printable

I will solve the probability problems on this worksheet by analyzing each spinner and calculating the probabilities based on the number of pieces for each color.

Let's start with the first spinner at the top.

First Spinner (Top)

- Question 1: How many pieces are there total in the spinner?
- I can count the sections in the spinner. It is divided into 8 equal pieces.

- Question 2: If you spun the spinner 1 time, what is the probability it would land on a white piece?
- I need to count how many white pieces there are. From the image, I can see 4 white pieces.
- The probability is calculated as the number of favorable outcomes (white pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{4}{8} = \frac{1}{2} $.

- Question 3: If you spun the spinner 1 time, what is the probability it would land on a black piece?
- I need to count how many black pieces there are. From the image, I can see 2 black pieces.
- The probability is calculated as the number of favorable outcomes (black pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{2}{8} = \frac{1}{4} $.

Now, let's move to the second spinner.

Second Spinner

- Question 1: How many pieces are there total in the spinner?
- I can count the sections in the spinner. It is divided into 8 equal pieces.

- Question 2: If you spun the spinner 1 time, what is the probability it would land on a blue piece?
- I need to count how many blue pieces there are. From the image, I can see 4 blue pieces.
- The probability is calculated as the number of favorable outcomes (blue pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{4}{8} = \frac{1}{2} $.

- Question 3: If you spun the spinner 1 time, what is the probability it would land on a white piece?
- I need to count how many white pieces there are. From the image, I can see 4 white pieces.
- The probability is calculated as the number of favorable outcomes (white pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{4}{8} = \frac{1}{2} $.

Next, let's analyze the third spinner.

Third Spinner

- Question 1: How many pieces are there total in the spinner?
- I can count the sections in the spinner. It is divided into 10 equal pieces.

- Question 2: If you spun the spinner 1 time, what is the probability it would land on a green piece?
- I need to count how many green pieces there are. From the image, I can see 6 green pieces.
- The probability is calculated as the number of favorable outcomes (green pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{6}{10} = \frac{3}{5} $.

- Question 3: If you spun the spinner 1 time, what is the probability it would land on a purple piece?
- I need to count how many purple pieces there are. From the image, I can see 2 purple pieces.
- The probability is calculated as the number of favorable outcomes (purple pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{2}{10} = \frac{1}{5} $.

Finally, let's look at the fourth spinner.

Fourth Spinner

- Question 1: How many pieces are there total in the spinner?
- I can count the sections in the spinner. It is divided into 10 equal pieces.

- Question 2: If you spun the spinner 1 time, what is the probability it would land on a blue piece?
- I need to count how many blue pieces there are. From the image, I can see 8 blue pieces.
- The probability is calculated as the number of favorable outcomes (blue pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{8}{10} = \frac{4}{5} $.

- Question 3: If you spun the spinner 1 time, what is the probability it would land on a white piece?
- I need to count how many white pieces there are. From the image, I can see 2 white pieces.
- The probability is calculated as the number of favorable outcomes (white pieces) divided by the total number of outcomes (total pieces).
- So, the probability is $ \frac{2}{10} = \frac{1}{5} $.
