Derivation of conditional probability formula

WebLinear Interpolation Formula. This formula finds the best fit curve as a straight line using the coordinates of two given values. Then every required value of y at a known value of x will be obtained. The first coordinates are x1 and y1. The second coordinates are x2 and y2. The interpolation point is x, and the interpolated value is y. Thus, the conditional probability P ( D1 = 2 D1 + D2 ≤ 5) = 3⁄10 = 0.3: Here, in the earlier notation for the definition of conditional probability, the conditioning event B is that D1 + D2 ≤ 5, and the event A is D1 = 2. We have as seen in the table.
