Key formulas for probability calculation include:

Single Event Probability: \( P(A) = \frac{n(A)}{n(S)} \)

Multiple Event Probability (mutually exclusive): \( P(A \cup B) = P(A) + P(B) \)

Multiple Event Probability (independent): \( P(A \cap B) = P(A) \times P(B) \)

Conditional Probability: \( P(A | B) = \frac{P(A \cap B)}{P(B)} \)

Probability is calculated as the ratio of favorable outcomes to the total number of possible outcomes.

The basic formula for probability is \( P(A) = \frac{n(A)}{n(S)} \), where \( P(A) \) is the probability of an event A.

Identify the total number of possible outcomes and the number of ways the event can occur, then use the probability formula.

Enter the number of favorable outcomes and the total number of outcomes into the probability calculator to find the probability.

The four types of probability are theoretical, experimental, subjective, and axiomatic probability.

For simple cases, list all possible outcomes. For complex scenarios, use combinatorial methods like permutations and combinations.

Start with basic examples like coin tosses or dice rolls and progress to more complex scenarios to understand probability concepts.

Basic probability is the likelihood of an event occurring, calculated as the ratio of favorable outcomes to total possible outcomes.

The basic rules include that the probability of any event ranges from 0 to 1, and the sum of probabilities of all possible outcomes equals 1.

An example is calculating the likelihood of drawing a specific card from a deck, or the probability of a certain roll on a dice.

For a simple event, the formula is \( P(A) = \frac{n(A)}{n(S)} \), where \( A \) is the event.

Use the formula \( 1 - P(\text{not happening}) \) to calculate the probability of an event occurring at least once.
