homework 5 section 10.1 question 2 of 8 (1 point) | question attempt: 1 of unlimited (b) subtract. 1 - p(not x) =

Explanation:

Step1: Substitute the value of $P(\text{not }X)$

We know that $P(\text{not }X)=\frac{7}{10}$, so we substitute it into the expression $1 - P(\text{not }X)$.
$1-\frac{7}{10}$

Step2: Calculate the result

We rewrite $1$ as $\frac{10}{10}$, then subtract. $\frac{10}{10}-\frac{7}{10}=\frac{10 - 7}{10}=\frac{3}{10}$

Answer:

$\frac{3}{10}$
