Explanation:

Step1: Recall the rule for unusual events

An event is considered unusual if its probability \( P(x) < 0.05 \).

Step2: Check the probability for \( x = 0 \)

From the table, the probability of a household having no HD televisions (\( P(0) \)) is \( 0.030 \).

Step3: Compare with 0.05

Since \( 0.030 < 0.05 \), the event of a household having no HD televisions is unusual.

Answer:

A. It would be unusual because the probability of having no HD televisions is less than 0.05.
