For a valid discrete probability distribution, the range condition is [...]\text{[...]}[...], and the total condition is ∑P(X=x)=1\sum P(X=x)=1∑P(X=x)=1.
A
k=0.30k=0.30k=0.30.
B
λ=2\lambda=2λ=2.
C
It counts the arrangements of the rrr successes.
D
For a valid discrete probability distribution, the range condition is 0≤P(X=x)≤1\boxed{0\le P(X=x)\le 1}0≤P(X=x)≤1, and the total condition is ∑P(X=x)=1\sum P(X=x)=1∑P(X=x)=1.
