Spinner 1:

Colors: Gray, Black, White (with 6 total sections)

Looking at the first spinner:
- It is divided into 6 equal pieces.
- White pieces: 2
- Black pieces: 2
- Gray pieces: 2

#### Questions:

1. How many pieces are there total in the spinner?
→ There are 6 pieces.

2. What is the probability it would land on a white piece?
→ Number of white pieces = 2
→ Total pieces = 6
→ Probability = $ \frac{2}{6} = \frac{1}{3} $

3. What is the probability it would land on a black piece?
→ Number of black pieces = 2
→ Probability = $ \frac{2}{6} = \frac{1}{3} $

✔ Answers for Spinner 1:
1. 6
2. $ \frac{1}{3} $
3. $ \frac{1}{3} $

→ 8

2. Probability of landing on a blue piece?
→ $ \frac{4}{8} = \frac{1}{2} $

3. Probability of landing on a white piece?
→ $ \frac{4}{8} = \frac{1}{2} $

✔ Answers for Spinner 2:

📌 Explanation of Probability:

Probability = $ \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} $

Each section is equal in size, so every section has an equal chance of being landed on.

We counted the number of sections of the desired color and divided by the total number of sections.

This gives us the theoretical probability.
