Question

(b) subtract.
1 - p(not x) =

(c) select the answer that makes the sentence true.
1 - p(not x) is the same as select

Explanation:

Step1: Recall probability rule

The sum of the probability of an event $X$ and the probability of its complement (not $X$) is 1, i.e., $P(X)+P(\text{not }X)=1$.

Step2: Solve for $1 - P(\text{not }X)$

From $P(X)+P(\text{not }X)=1$, we can rewrite it as $P(X)=1 - P(\text{not }X)$.

Answer:

(b) $P(X)$
(c) $P(X)$
