Simple probability helps us figure out how likely something is to happen. Let’s break it down into easy steps.

1. What is Probability?
   Probability is a number that ranges from 0 to 1.

• A probability of 0 means something can't happen at all.
• A probability of 1 means it definitely will happen.
  For example, if we say there’s a probability of 0.5 (or 50%) that it will rain today, it means there’s an equal chance of it raining or not raining.

2. How Do We Calculate It?
   The formula for finding simple probability is:

   Probability of an Event = Number of Favorable Outcomes / Total Number of Possible Outcomes

3. A Simple Example
   Imagine you have a bag with 3 red marbles and 2 blue marbles.
   If you pick one marble at random, the total number of marbles is 3 + 2 = 5.
   So, the probability of picking a red marble is:

   Probability (Red) = 3 / 5 = 0.6 or 60%

4. Another Example
   If you roll a regular six-sided die, the probability of rolling a 4 is:

   Probability (4) = 1 / 6 ≈ 0.17 or 17%

Understanding simple probability helps us make better choices based on how likely different things are to happen!
