Is it possible, impossible, or
certain that someone watches television four times a week?
This question is all about the
likelihood of something happening. Is it possible that it will
happen? Is it completely impossible? Or is it absolutely certain? We can use these words to describe
the probability of something happening. And the event that this question is
talking about is someone watching television four times a week. Let’s have a think about our three
possible answers. If it’s certain that someone
watches television four times a week, then it’s always true that they watch
television four times every week, never any less, never anymore.
If we say that something’s
impossible, we’re saying that there’s no chance of it happening. It’s not even possible that someone
could watch television four times a week. And then we’ve got the word
“possible.” If a statement like this is
possible, then there’s a chance that it could happen. It might not happen, but there’s a
chance that it could. I wonder, how many times do you
watch television a week? Although some people might watch
television four times a week, we can’t say that it’s always true, can we? But we can’t say that it’s never
true, either. When something’s impossible,
there’s no chance of it happening.
Of course, there is some
possibility that someone could watch television four times a week. It’s quite easy to do really, isn’t
it? The only word we can really use to
describe this event is “possible.” It’s possible that someone watches
television four times a week, and it’s possible that they don’t. It’s a statement that’s sometimes
true. Maybe it’s true of you. Maybe it’s not. It’s possible that someone watches
television four times a week.
