How to Calculate P Value in Excel: Step-by-Step Guide (2024)
WebSep 17, 2015 · Explanation: In order to find the value of P ( − 3) you need to divide the P (x) with x + 3 hence. P (x) = x3 + 3x2 − x −8 = (x + 3) ⋅ k(x) +q(x) or x3 +3x2 − x − 8 = (x2 − 1) ⋅ … WebAccording to the remainder theorem, when a polynomial p(x) (whose degree is greater than or equal to 1) is divided by a linear polynomial x - a, the remainder is given by r = p(a). i.e., to find the remainder, follow the steps below:. Find the zero of the linear polynomial by setting it to zero. i.e., x - a = 0 ⇒ x = a.; Then just substitute it in the given polynomial. WebJan 5, 2024 · Mutually Exclusive Events: P(A∪B) = P(A) + P(B) If A and B are not mutually exclusive, then the formula we use to calculate P(A∪B) is: Not Mutually Exclusive Events: P(A∪B) = P(A) + P(B) - P(A∩B) Note that P(A∩B) is the probability that event A and event B both occur. The following examples show how to use these formulas in practice. income and health statistics
