A recent study conducted by a health statistics center found that 24% of households in a certain country had no landline service.

Complete parts a) through c) below.
What is the probability that all three, of them have a landline?
What is the probability that at least one of them does not have a landline?
What is the probability that at least one of them does have a landline?
