FAQs

What is the formula for the sum of an arithmetic series?

The sum of an arithmetic series is calculated as Sn = n/2 * (a1 + an), where n is the number of terms, a1 is the first term, and an is the last term.

How is independence between two events defined in probability?

Two events A and B are independent if P(A ∩ B) = P(A) * P(B) or P(A|B) = P(A).

What are the cubic factorization formulas?

The cubic factorization formulas are a^3 + b^3 = (a + b)(a^2 - ab + b^2) and a^3 - b^3 = (a - b)(a^2 + ab + b^2).
