If 3 squares are chosen at random from the 64 squares of a chess board, then the probability that all of them lie along the same diagonal line is
- A \(\frac{21}{764}\)
- B \(\frac{14}{745}\)
- C \(\frac{7}{744}\)
- D \(\frac{7}{736}\)
Answer & Solution
Correct Answer
(C) \(\frac{7}{744}\)
Step-by-step Solution
Detailed explanation
\(\text{Total ways to choose 3 squares} = \binom{64}{3} = \frac{64 \times 63 \times 62}{3 \times 2 \times 1} = 41664\)…
