We have been working on probability stuff over the two weeks. It had been a blast! Probability is pretty much statatics. It tells you what the odds or chances of something happening or not happening will be. Your answer will always be in between 0-1 and is also a fraction. The final answer of your fraction should be simplified. Some of the most common types of probability is dealing with dice or a deck of cards. I'm going to show you an example of each.

Example 1. What are the odds of drawing a diamond or a club out of a standard deck of 52 cards.
They're 13 diamonds and 13 clubs in a deck of cards. So you would put 13/52 + 13/52 which simplifies to 1/2. That would be your final answer.

Example 2. What are the odds that you roll higher than a a multiple of 2 when rolling a six sided die
Since there are 3 sides that are multiples of 2(2,4,6) and six total sides you would do 3/6 which simplifies to 1/2. That would be your final answer.

Probability is pretty easy once you get used to it.

Make it a great day or not, the choice is yours :)
