Real-life examples of theoretical probability are all around us. Here are some easy examples to understand:

1. Coin Tossing:

   • When you toss a coin, it can land on heads or tails.
   • The chances are equal:
     • Chance of heads: 1 out of 2
     • Chance of tails: 1 out of 2

2. Rolling a Die:

   • When you roll a six-sided die, you can get any number from 1 to 6.
   • If you want to know the chance of rolling a specific number, like 4, it’s:
     • Chance of getting a 4: 1 out of 6

3. Drawing Cards:

   • If you pick a card from a regular deck of 52 cards, you might want to find the chance of picking an Ace.
   • There are 4 Aces in the deck, so the chance is:
     • Chance of drawing an Ace: 4 out of 52, or simplified to 1 out of 13

4. Marble Selection:

   • Imagine you have a bag with 3 red marbles and 2 blue marbles.
   • To find the chance of picking a red or blue marble:
     • Chance of picking a red marble: 3 out of 5
     • Chance of picking a blue marble: 2 out of 5

These examples show how we can figure out the chances of different outcomes happening.
