माना \(66\) योगफल के दो धनात्मक पूर्णाकों का अधिकतम गुणनफल \(M\) है। माना, प्रतिदर्श समष्टि \(S=\left\{x \in Z: x(66-x) \geq \frac{5}{9} M\right\}\) तथा घटना \(\mathrm{A}=\{\mathrm{x} \in \mathrm{S}: \mathrm{x}, 3\) का एक गुणज है \(\}\) तो \(\mathrm{P}(\mathrm{A})\) बराबर है

  1. A \(\frac{15}{44}\)
  2. B \(\frac{1}{3}\)
  3. C \(\frac{1}{5}\)
  4. D \(\frac{7}{22}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\frac{1}{3}\)

Step-by-step Solution

Detailed explanation

\(M=33 \times 33\) \(x(66-x) \geq \frac{5}{9} \times 33 \times 33\) \(11 \leq x \leq 55\) \(A:\{12,15,18, \ldots .54\}\) \(P(A)=\frac{15}{45}=\frac{1}{3}\)
