1.A 500 N Force has a line of action that passes through the point (0,0,0) and (3m,3m,0). The Magnitude of the Moment that the Force causes about an axis that passes through points (0,5m,5m) and (10m,10m,10m) is most nearly: (a) 1021 N-m; (b) 1443 N-m; (c) 3062 N-m; (d) 6124 N-M.
2.Suppose 76% of all commuters ride to work in carpools. if eight workers are randomly selected, find the probability that at least 7 will ride in carpools.
