Answer

Explanation:

Step1: Recall probability formula

The probability of an event $A$ not occurring, denoted as $P(\overline{A})$, is given by $P(\overline{A})=1 - P(A)$. Here, event $A$ is the bill being paid on - time. We know from part (a) that $P(A) = 0.6378$.

Step2: Calculate non - on - time probability

$P(\overline{A})=1 - 0.6378$ $P(\overline{A}) = 0.3622$

Answer:

$0.3622$
