चार कुर्सियों में 10 व्यक्तियों को बैठाने के तरीकों की संख्या
प्रयुक्त सूत्र:
nPr = n!/(n – r)!
जहाँ, n = व्यक्तियों की संख्या
r = कुर्सियों की संख्या
गणना:
प्रश्न के अनुसार
nPr = n!/(n – r)!
⇒ 10!/(10 – 4)!
⇒ 10!/6!
⇒ (10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)/(6 × 5 × 4 × 3 × 2 × 1)
⇒ (10 × 9 × 8 × 7)
⇒ 5040
∴ अभीष्ट मान 5040 है।
