To find probabilities on a scale from 0 to 1, just follow these simple steps. This scale helps us see how likely something is to happen.

Step 1: Know the Probability Scale

The probability scale goes from 0 to 1:

• 0 means an impossible event (like rolling a 7 on a six-sided die).
• 1 means a certain event (like the sun rising tomorrow).
• Any number in between shows different chances. For example, a probability of 0.5 means it's equally likely to happen or not happen.

Step 2: Identify Possible Outcomes

When we look at an event, we need to find all possible outcomes. For example, if you flip a coin, there are two results: Heads (H) or Tails (T).

Step 3: Count Favorable Outcomes

Next, count how many outcomes are good for what you want. For our coin flip, if we want Heads, there’s 1 good outcome (H).

Step 4: Calculate Total Outcomes

Now, count all possible outcomes. For the coin flip, there are 2 possible outcomes: H and T.

Step 5: Use the Probability Formula

Now we can use the probability formula:

$$\text{Probability} = \frac{\text{Number of Favorable Outcomes}}{\text{Total Outcomes}}$$

In our example:

$$\text{Probability (H)} = \frac{1}{2} = 0.5$$

Step 6: Understand the Result

Finally, let’s understand what this result means. A probability of 0.5 shows there is a 50% chance of getting Heads when you flip the coin.

By following these steps, you’ll be ready to calculate probabilities and understand what they mean on the scale from 0 to 1!
