Probability Expressions and Applications

P(A) = 0.5
Basic probability – probability of event A occurring

P(A|B) = 0.3
Conditional probability – probability of A given B

E[X] = μ
Expected value – mean of random variable X

Var(X) = σ²
Variance – measure of spread for random variable X

P(A∪B) = P(A) + P(B) – P(A∩B)
Addition rule for union of two events

C(n,k) = n! ÷ (k!(n-k)!)
Combinations formula – number of ways to choose k items from n
