A spider and a fly move along a straight line in unit increments. the spider always moves towards the fly by one unit. the fly moves towards the spider by one unit with probability 0.3, moves away from the spider by one unit with probability 0.3, and stays in place with probability 0.4. the initial distance between the spider and the fly is integer. when the spider and the fly land in the same position, the spider captures the fly. (a) construct a markov chain that describes the relative location of the spider and fly. (b) identify the transient and recurrent states.
