GATE 2025 ST – Question 28

Probability · Random Variables and Transforms · 1 mark · Numerical answer

X has CDF F with lim_(h→0−)F(3+h)=1/4 and F(3)=3/4. Find 16P(X=3) (integer).

Show answer and explanation

Correct answer: 8 to 8

Explanation

The point mass is the jump F(3)−F(3−)=3/4−1/4=1/2. Multiplying gives **8**.
