Explain the Basic Rules of this Probability Condition P(A or B) = P(A)+P(B)-P(A and B).
If A and B are mutually exclusive then P(A and B) = 0 and
P(A or B) = P(A)+P(B).

He expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. if the length is fraction 2 over 3 unit and the width is fraction 1 over 3 unit, what is the perimeter of the rectangle in units? fraction 2 over 3 unit 1 unit 1fraction 2 over 3 units 2 units
