TS EAMCET · Maths · Probability
If probability function of a discrete random variable \(X\) is \(P(X=r)=r / k, r=1,2,3,4,5\), then \(P\left(X=2\right.\) or \(\left.X=\frac{k}{3}\right)\), is
- A \(P(X=1\) or \(X=6)\)
- B \(P\left(X=4\right.\) or \(\left.X=\frac{k}{5}\right)\)
- C \(P\left(x=\frac{k}{5}\right.\) or \(\left.x=5\right)\)
- D \(P\left(x=\frac{k}{3}\right.\) or \(\left.x=0\right)\)

Assertion (A): For \(x \in \mathbb{R}-\{1\}, \frac{d}{d x}\left(\operatorname{Tan}^{-1}\left(\frac{1+x}{1-x}\right)\right)=\frac{d}{d x}\left(\operatorname{Tan}^{-1} x\right)\)
Reason (R): For \(x < 1, \operatorname{Tan}^{-1}\left(\frac{1+x}{1-x}\right)=\frac{\pi}{4}+\operatorname{Tan}^{-1} x\),
for \(x>1, \operatorname{Tan}^{-1}\left(\frac{1+x}{1-x}\right)=-\frac{3 \pi}{4}+\operatorname{Tan}^{-1} x\)
