The distribution function \(\mathrm{F}(\mathrm{X})\) of discrete random variable \(\mathrm{X}\) is given by
Then \(P[X=4]+P[X=5]=\)
- A 0.14
- B 0.85
- C 0.37
- D 0.23
Answer & Solution
Correct Answer
(C) 0.37
Step-by-step Solution
Detailed explanation
We have
\(\therefore P(x=1)=0.2, P(x=2)=0.17, P(x=3)=0.11\)
\(P(x=4)=0.14, P 9 x=5)=0.23, P(x=6)=0.15\)
Thus \(\mathrm{P}(\mathrm{x}=4)+\mathrm{P}(\mathrm{x}=5)=0.14+0.23=0.37\)
\(\therefore P(x=1)=0.2, P(x=2)=0.17, P(x=3)=0.11\)
\(P(x=4)=0.14, P 9 x=5)=0.23, P(x=6)=0.15\)
Thus \(\mathrm{P}(\mathrm{x}=4)+\mathrm{P}(\mathrm{x}=5)=0.14+0.23=0.37\)
