## Video transcript

- Hey, Sal. - Hello, Brit. - I would like to propose a game to play. - (laughing) All right. - I have eight chips here. - All right, yeah, I see that. - And I have a fair coin, feel
- Eight chips. - Go ahead and inspect it.
- Fair coin. Seems very fair to me. - You need to pick if
you want heads or tails. - I like heads. - K, heads. Okay, I like tails. - All right. - Here's the game, we're
gonna flip the coin. The first one to win three
games takes the whole pot. - The first one to get
to three, so the first, if there's three heads, first,
before we get to three tails, I get it all. Three tails before we get to
three heads, you get it all. - Yeah, maybe we could even
keep a tally as we play. - Okay, sounds, sounds good.
- Heads, heads versus tails. Okay, let's play. - All right, let's do it. - We'll take turns flipping, because, you know, you never know. - Heads.
- Heads. - I'll try to flip with style. - (both) Tails. - Dang. Heads. - Heads, I'm doin' good. (bell rings) - Oh, dinner bell. I gotta go. - No, hey, that, look,
I'm, I'm about to win. - I had a good run at
the beginning, you know, I usually, I, I start slow
- At the beginning. - in games like this. I'm always strong finisher. - Yeah, but look, if the next
flip is heads, I get it all. - Okay, how 'bout we split the pot, okay? Split the pot, you get a
little bit, I get a little bit, we both go home happy. - I get a lot of bit.
- Good idea. - A lot of bit. (laughs) How 'bout we just split the pot? - No, 'cause I have a higher
chance of winning than you do. - How are we ever gonna
figure that out exactly? Let's just split the pot and call it even. - Let's think about it this way.
