Download Solution PDFप्रयुक्त अवधारणा:
किसी घटना की प्रायिकता P(E) = (अनुकूल परिणामों की संख्या) ÷ (प्रतिदर्श समष्टि)
गणना:
संभावित कुल संख्या = 63
अब,
अनुकूल परिणामों की संख्या = (1, 1, 3), (1, 2, 2), (1, 3, 1), (2, 1, 2), (2, 2, 1), (3, 1, 1)
कुल अनुकूल परिणाम = 6
इसलिए, अभीष्ट प्रायिकता = 6/216
⇒ 1/36
∴ अभीष्ट उत्तर 1/36 है।
