Why can a defective component be labelled a success?
A
Trials become dependent because the success probability changes.
B
P(X=4)P(X=4)P(X=4)
C
A success is the outcome being counted, not necessarily desirable.
D
For integer-valued XXX, an upper-tail probability is calculated using P(X≥r)=1−P(X≤r−1)\boxed{P(X\ge r)=1-P(X\le r-1)}P(X≥r)=1−P(X≤r−1).
