Chapter 24, Problem 24.3(choose chapter or problem)
You may wonder whether in (16) the last relation follows from the others. but the answer is no. To see this. imagine that a chip is drawn from a box containing 4 chips numbered 000,01 I. 101, 110. and let A. B. C be the events that the first. second. and third digit. respectively. on the drawn chip is 1. Show that then the first three formulas in (16) hold but the last one does not hold.
