Creating a good probability table can be easy if you follow these simple steps. These steps help you show data clearly and understand the chances of different outcomes. Let’s break it down:

1. Define the Experiment

Start by explaining what the experiment is about. This could be flipping a coin or rolling a die. Each of these actions has specific results we need to think about.

2. List Possible Outcomes

Write down all the things that could happen during the experiment.

For a coin flip, the possible results are Heads (H) and Tails (T).

If you roll a six-sided die, the outcomes are: 1, 2, 3, 4, 5, 6.

3. Determine Event Probabilities

Now, we need to figure out the chances for each outcome.

For a fair coin:

• Chance of Heads (H) = 1 out of 2 (or 50%)
• Chance of Tails (T) = 1 out of 2 (or 50%)

For a fair six-sided die:

• Chance of each number (1, 2, 3, 4, 5, or 6) = 1 out of 6 (or about 16.67%)

4. Create the Probability Table

Make a table to show the outcomes and their chances.

For the coin:

| Outcome | Probability | |---------|-------------| | H | 0.5 | | T | 0.5 |

For the die:

| Outcome | Probability | |---------|-------------| | 1 | 0.1667 | | 2 | 0.1667 | | 3 | 0.1667 | | 4 | 0.1667 | | 5 | 0.1667 | | 6 | 0.1667 |

5. Check for Completeness

Make sure the total of all probabilities adds up to 1.

For the coin, adding up gives us: 0.5 (Heads) + 0.5 (Tails) = 1.

For the die, it would be: 0.1667 + 0.1667 + 0.1667 + 0.1667 + 0.1667 + 0.1667 = 1.

6. Interpret the Data

Lastly, use your probability table to help you make choices or predictions.

This will help you understand more about the experiment and what could happen next. The information in the table can guide your further thinking and help you draw conclusions.
