1. [CLO-1(C3)] Kabaddi is a popular sport in South Asia. The basic rules of Kabaddi are simple: two teams of seven players each face off in a large square arena for two halves of twenty minutes each. Players from each team take turns running across the center line to the other team's half of the court ( called "raiding"), tagging members of the other team (4 people defending), and running back. The more opposing team members they tag, the more points they score (+1 point for each player he tags), but if the opposing team can physically prevent them from crossing back to their side of the court, they score no points. During the sports week, a kabaddi match is going to be scheduled between the students of Section A and C. Section A has 42 students while Section C has 35 students (a) In how many ways can a team from each of the class be selected. (3) (b) During the match there is 15% chance of a player being injured in which case a replace- ment has to be sent in. How many students should be put on bench (including the 7 players) for each team so that there is 95% probability of having enough replacement players for the entire match. (3) (c) During a raid, there is 10% chance of tagging an opposing team member and success- fully returning back, 40% chance of being caught by that player and 50% chance of returning back without tagging. What is probability of scoring 1 point for the raid. What is the probability of scoring 4 points for the raid. Assume that the raider deals with each defender independently. (4)
