Detailed Solution
Download Solution PDFसंकल्पना:
एक घटना के घटित होने की प्रायिकता =
यदि एक पासे को उछाला जाता है, तो प्रतिदर्श समष्टियों की संख्या = 6 है, यदि दो पासे को उछाला जाता है, तो n(S) = 62 = 36 है।
गणना:
यहाँ, चार पासे को उछाला जाता है,
n(S) = 64
अब, उनपर दिखाई देने वाली संख्या का योग 25 = { }
⇒ n = 0
(∵अधिकतम योग = 6 + 6 + 6 + 6 = 24)
∴ प्रायिकता = 0/(64) = 0
अतः विकल्प (1) सही है।
