What Exactly is Probability?

Probability quantifies the likelihood of an event occurring. It indicates whether it will transpire or not.

Understanding Probability

You might be aware that probability is a field of mathematics focused on the examination of random events. It is already recognised that the result of a random occurrence cannot be forecasted until it takes place, but probability allows us to determine the likelihood of this occurrence.

Probability Foundation

Probability operates on the foundation of logical elements and enables us to assess whether an event will have a high or low likelihood of happening. You may also discover that the event will be dependent or independent of the previously occurred events through the concept of probability.

How to Calculate Probability?

1

Identify the Event

Examine the probability of an event that has at least one potential outcome. For instance, consider the possible outcomes of flipping a coin: you will either obtain heads or you will not obtain heads.

2

Count Total Outcomes

After this, you should be able to identify the total results for the past analysed event. In the scenario of flipping a coin, the total number of results is 2. This is either heads or tails.

3

Calculate the Ratio

Finally, divide the likelihood of an event's occurrence by the overall number of results. Continuing with the current example, the possible number of obtaining heads after flipping a coin is 1, while the total number of results is 2. Therefore, the probability of getting heads can be calculated as 1/2, which equals 0.5.

Probability Examples

Coin Flip Example:

Favorable outcomes: 1 (getting heads)
Total outcomes: 2 (heads or tails)
Probability: 1/2 = 0.5 or 50%

Dice Roll Example:

Favorable outcomes: 1 (getting a 6)
Total outcomes: 6 (numbers 1-6)
Probability: 1/6 ≈ 0.167 or 16.7%

Key Probability Formulas

Basic Probability: P(A) = Number of favorable outcomes / Total number of outcomes

Complement: P(A') = 1 - P(A)

Union: P(A∪B) = P(A) + P(B) - P(A∩B)

Conditional: P(A|B) = P(A∩B) / P(B)
