Step 2 ：The probability of a household having no HD televisions is given as 0.010.
Step 3 ：Generally, an event is considered unusual if its probability is less than 0.05.
Step 4 ：Comparing the given probability with 0.05, we find that 0.010 is less than 0.05.
Step 5 ：\(\boxed{\text{Therefore, it would be unusual for a household to have no HD televisions.}}\)
