How to remember Probability formulas for a longer time?
One of the significant benefits of understanding Probability formulas is the capability to quickly and accurately address simple formula-based questions.
Following are the techniques you can use to memorise Probability formulas:
For a start, you can start understanding the concepts of Probability. It will help you find out why a formula is used.
Keep a separate piece of paper and write down each formula on the Probability topic you need to memorise.
Write down and examine each Probability formula, but this time with intervals. Write the equation, then take a 2-minute break to think about it before writing it again.
Your memory is more likely to associate with the formula you want to remember if you use it more often. Solve the problems employing the formula.
Visualise and repeat out loud the formula occasionally. Create Probability formulas flashcards to help with this. You can also use these flashcards while practicing the Probability questions.
The formula should be written down and posted somewhere you will see daily. They'll be subconsciously imprinted into your memory.
How conceptual understanding of Probability topic helps in remembering its formulas?
Conceptual understanding will help you to make sense of the Probability formulas. Conceptual understanding is concentrated on describing why things happen as opposed to how to make them happen. They help you understand the true motive for employing the Probability formulas.
