XAT 2017 — Decision Making Question 14
Analyse the following caselet and answer the question that follows:
A University coach was asked to select teams in three sports: Shooting, Cricket (batsmen only) and “Snakes & Ladder”. The honest and keen observer head boy of the school informed the coach that he had observed 100 students playing the three games – shooting, cricket and “Snakes & Ladder”. In shooting, all students were given 100 chances to hit a target. In cricket, a batsman faced a maximum of 100 balls, provided he DID NOT GET OUT. In “Snakes & Ladder”, every student could play 100 matches, one each with the other students and one against a computer. In shooting, a player got one point for hitting the target and zero point for missing the target. In cricket, a batsman got one point for hitting the ball and zero point for missing it. In “Snakes & Ladder”, a person got one point for winning the game and zero for losing. To the coach’s utter surprise, the distribution of points across all three games was the same. It was as follows:
âââââââ
The coach has to select a team of eleven in each sport.
Which of the following options is the best way to select the “Snakes & Ladder” team?
Answer & solution
- A
The coach must select all students between 80 and 99.
- B
The coach must select both the students between 90 and 99.
- C
The coach must select at least 6 students between 40 and 59.
- D
The coach must not select students between 0 and 9.
The coach can ignore the data in the table and randomly pick any 11 prayers.
In snakes and ladder, the player doesn’t exhibit any skill and it is of pure luck. So, the past data in the table has no relevance for selection. Hence, the best selection process should give equal opportunity to everyone.
Hence, option (e).
