In a Binomial distribution, if \(p=q\) and \(n \geq 4\), then \(2^n P(X=5)=\)
- A \(5\)
- B \({ }^n \mathrm{C}_2\)
- C \(10\)
- D \({ }^n C_5\)
Answer & Solution
Correct Answer
(D) \({ }^n C_5\)
Step-by-step Solution
Detailed explanation
Given, \(p=q\) \(\begin{aligned} & \because \quad p+q=1 \\ & \Rightarrow \quad p=q=\frac{1}{2}\end{aligned}\) Now, \(2^n P(X=5)\)…
