In Aggressive Behаviоr, zооlogists investigаted the likelihood of fаllow deer bucks fighting during the mating season. During a 270-hour observation period, the researchers recorded 205 encounters between two bucks. Of these, 167 involved one buck clearly initiating the encounter with the other buck. In these 167 initiated encounters, the zoologists kept track of whether a physical contact fight occurred and whether the initiator won or lost the fight. The buck that was driven away by the other buck was considered the loser. A summary of the 167 initiated encounters is provided in the table below. Initiator wins No clear winner Initiator loses Totals Fight 26 23 15 64 No fight 80 12 11 103 Totals 106 35 26 167 Suppose we select one of these 167 encounters and note the outcome (fight status and winner). What is the probability that a fight occurs or the initiator loses?
