Answer
Explanation:
Step1: Recall probability rule
The probability of receiving the newspaper at least one day per week is $P(X\geq1)$. We know that $P(X\geq1)=1 - P(X = 0)$.
Step2: Read $P(X = 0)$ from graph
From the probability - distribution graph, $P(X = 0)=0.17$.
Step3: Calculate $P(X\geq1)$
$P(X\geq1)=1 - 0.17=0.83$.
