a. Sketch a sample space for the following experiment: A timber pile will be chosen from a supply of assorted lengths L, the longest of which is 60 ft. The pile will be driven into the ground in an area where the solid-rock-bearing stratum is at a variable depth D, the maximum being 60 ft. b. On a sequence of such sketches shade the following events (i) A (ii) B (iii) C = [L > 50] (iv) D = BU C = [there is some kind of relative difficulty] (v) E = BO C = [both kinds of difficulty arise] (vi) F (B U C) N A = [there is some kind of difficulty and the pile [pile of adequate length] [D > 50] = (it is a relatively long drive to bearing] [the pile is relatively difficult to handle] [L > D] %3D %3D %3! %3D %3D %3D %3D was of inadequate length]
