A dice is thrown then find the probability that 7 will turn up on the upper faces.

Answer

To solve the problem of finding the probability that a 7 will turn up on the upper face when a die is thrown, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: We need to find the probability of rolling a 7 on a standard six-sided die.

2. **Identify the Total Outcomes**: A standard die has six faces, numbered from 1 to 6. Therefore, when we throw the die, the total number of possible outcomes is 6.

\[ \text{Total Outcomes} = 6 \]

3. **Identify the Favorable Outcomes**: We need to determine how many outcomes are favorable for rolling a 7. Since a standard die only has the numbers 1, 2, 3, 4, 5, and 6, there are no faces with the number 7.

\[ \text{Favorable Outcomes} = 0 \]

4. **Apply the Probability Formula**: The probability \( P \) of an event is given by the formula:

\[ P(\text{Event}) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Outcomes}} \]

Substituting the values we found:

\[ P(7) = \frac{0}{6} = 0 \]

5. **Conclusion**: The probability of rolling a 7 on a standard die is 0.

### Final Answer:
The probability that 7 will turn up on the upper face when a die is thrown is **0**.
