Oh hi everybody! Today I am going to talk to you about probability. PROBABLY!
No, not probably, probability! PROBLABLABLABLY!
Actually you say it like this: probability! PROBABILITY!
Yay you got it! OK, so probability
is kind of like thinking about if something will happen, or won't happen, or will maybe happen.
For example, tomorrow I will eat dinner. I know that this is true
because I eat dinner every day. And if we know that something will happen we can also say
that it is certain. CERTAIN! Let’s say it together: certain. Yes, one more time: certain.
But I wonder what I will eat for dinner? Hmmm… what about rocks? I said rocks!
Do you think I will eat rocks for dinner? No I won’t eat rocks for dinner. I know this
because rocks are hard, and they do not taste good, and they could be very dangerous to eat. So I know
that I definitely won't eat rocks. And if we know that something won't happen, we can also say that it is
impossible. IMPOSSIBLE! Let’s say it together: impossible. Yes one more time: impossible.
So if I’m not going to eat rocks dinner, I wonder if I will eat a plate of spaghetti? You know,
I have had spaghetti before for dinner, and I like to eat spaghetti, so I think that
maybe I could eat spaghetti for dinner. And if we know that something will maybe happen, we can
also say that it is possible. POSSIBLE! Ya, let’s say it again: possible. Ya one more time: possible!
OK let’s take a break. I think it is a good time to… juggle! OK that’s enough!
So I am now going to tell you some things that could happen after dinner, and I want you to tell
me if you think that it is certain that it will happen, or if it is possible that it could maybe happen,
or if it is impossible, which means it won’t happen. Oh and by the way,
there are also many other words we can use when thinking about probability, for example
likely, and unlikely, and many others. But today I want to practice mostly the words
certain, possible, and impossible. OK, ready?
Situation # 1: After dinner, I will fall asleep. Do you think that this is certain, possible,
or impossible? Well, I fall asleep every night, so I think that this is something that is… certain!
Situation # 2: After dinner, I will fly to the moon and meet a dwarf named Betty.
Do you think that this is certain, possible, or impossible?
Well, I’ve never been to the moon before, and I don’t have a rocket ship, and
I don’t think dwarves live on the moon, so I think that this is something that is… impossible!
Situation # 3: After dinner, I will read a book. Do you think this is certain, possible, or impossible?
Well, I sometimes read a book before I go to bed, so I think that this is something that is… possible!
OK I now have some probability situations for you!
But first, let’s take another break and… juggle! OK that’s enough!
As I was saying, now I am going to say some things
about what you could do after your dinner. And you can tell me whether
they’re certain, possible, or impossible. One: After dinner, you will have dessert.
Two: After dinner, a unicorn will carry you to bed.
Three: After dinner, you will brush your teeth.
Four: After dinner, you will dream about unicorns.
OK, great answers everybody. And one thing I know for certain is that right now… it is time to juggle!
OK that's enough! OK, that is all the time we have for probability.

No it’s true. And I know that it is definitely possible to watch them. OK bye for now.
