Bayes

A footballer's chances of getting selected for the national team are determined by whether or not he has played consistently for his club team or is undergoing rehabilitation. The coach uses a player's performance during a club training session to determine whether or not the player will be selected to play for the club. The club coach also considers the physical condition of the player who is healthy and free of injuries. Players who have been injured will be placed in a rehabilitation programme. W (representing the national team), K (playing regularly for club teams), L (good player performance in training sessions), F (good physical condition), and R (representing the national team) are the variables to consider (participating in rehabilitation programs).

b)Assume the player is healthy, shown good performance in the training session and frequently played for his club. Show a Bayes' rule expression to calculate the probability that the player will be selected to play for his country.
