A concrete beam may fail either by shear (S) or flexure (F). Suppose that three failed beams are randomly selected and the type of failure iS determined for each one. Let X : the number of beams among the three selected that failed by shear. List each outcome in the sample space along with the associated value of X. S: FFF EFF FSF FFS FSS SFS 55F SSS x; Ii Ii ii ii ii ii iii LetX = the number of nonzero digits in a randomly selected 4digit PIN that has no restriction on the digits. What are the possible values ofX? O 0, 1, 2, 3, 4 o, 1,2,3,4, 1,2,3,4, 0,1,2,3 0000 1,2,3,4 For the following possible outcomes, give their associated X values. associated PIN value A branch of a certain bank has six ATMs. Let X represent the number of machines in use at a particular time of day.
