(20)Central Limit Theorem: Statement, Formula, Examples
The central limit theorem says that averages of large random samples follow a normal distribution, whatever the population looks like. This guide covers the statement, standard error, conditions, and six examples.
Probability A Intersection B Formula with Examples
The probability a intersection b formula is P(A ∩ B) = P(A) × P(B A), which becomes P(A)P(B) only when the events are independent. This article gives five worked examples.
Expected Value Formula with Worked Examples
The expected value formula is E(X) = ∑ x · P(x), each outcome multiplied by its probability and added. This article gives five worked examples.
Empirical Probability Formula with Examples
The empirical probability formula is P(E) = (number of times E occurred)/(total trials). This article gives five worked examples and the theoretical contrast.
Conditional Probability Formula with Examples
The conditional probability formula is P(B A) = (P(A ∩ B))/(P(A)), the probability of B once A is known. This article gives five worked examples.
Coin Toss Probability Formula with Examples
The coin toss probability formula gives any specific sequence of n fair tosses a probability of (1/2)ⁿ. This article gives five worked examples.
Prime Factorization Formula with Worked Examples
The prime factorization formula writes any integer above 1 as n = p₁ a₁ × p₂ a₂ × …, a product of prime powers. This article gives five worked examples.
Linear Interpolation Formula with Worked Examples
The linear interpolation formula is y = y₁ + ((x-x₁)(y₂-y₁))/(x₂-x₁), estimating a value between two known points. This article gives five worked examples.
Least Common Multiple Formula with Examples
The least common multiple formula is LCM(a,b) = (a × b)/(HCF(a,b)). This article gives the prime factorisation method, five worked examples, and the common errors.
Inverse Variation Formula - Definition and Examples
The inverse variation formula is y = k/x, equivalently xy = k, so one quantity falls as the other rises. This article gives five worked examples.
