PYQ Practice Set
Every usable probability question we could find in the CGL and CHSL Tier 2 papers, 11 in all: 4 from CGL 2022, 1 each from CGL 2023, 2024 and 2025, and 4 from CHSL Tier 2. A Tier 2 paper usually has only one or two probability questions, and most of them put two or three events together: two players aiming at a target, two people telling the truth, three students trying the same problem, or students choosing subjects. Write down each person's chance of “yes” and of “no” before you multiply anything. Give it about 11 minutes; 9 or more right is a good score.
