Fighting probability of fallow deer bucks. Refer to the Aggressive Behavior (Jan./Feb. 2007)… 1 answer below »

Fighting probability of fallow deer bucks. Refer to the Aggressive Behavior (Jan./Feb. 2007) study of fallow deer bucks fighting during the mating season, presented in Exercise 3.57 (p. 133). Recall that researchers recorded 167 encounters between two bucks, one of which clearly initiated the encounter with the other. A summary of the fight status of the initiated encounters is provided in the accompanying table. Suppose we select 1 of these 167 encounters and note the outcome (fight status and winner).
a. Given that a fight occurs, what is the probability that the initiator wins?
b. Given no fight, what is the probability that the initiator wins?
c. Are the events “no fight” and “initiator wins” independent?
Exercise 3.57
Fighting probability of fallow deer bucks. In Aggressive Behavior (Jan./Feb. 2007), zoologists investigated the likelihood of fallow 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. In these 167 initiated encounters, the zoologists kept track of whether or not a physical contact fight occurred and whether the initiator ultimately won or lost the encounter. (The buck that is driven away by the other is considered the loser.) A summary of the 167 initiated encounters is provided in the accompanying table. Suppose we select one of these 167 encounters and note the outcome (fight status and winner).
a. What is the probability that a fight occurs and the initiator wins?
b. What is the probability that no fight occurs?
c. What is the probability that there is no clear winner?
d. What is the probability that a fight occurs or the initiator loses?
e. Are the events “No clear winner” and “initiator loses” mutually exclusive?
