# Game Theory: What is an 'Optimal Mixed Strategy'? Watch

1. I missed the lesson where we covered this, and I've only just realised it! It looks pretty complicated, so I'm slightly concerned at the moment?

Can anyone help me out?

Thanks
2. If it makes any difference, I'm taking AQA mathematics, and this is for the D2 exam in June.
3. I didn't take D2 or AQA, but I do know a bit of computer science - take this with a pinch of salt!
A "pure strategy" is pretty much one in which there is no randomness involved, while a "mixed strategy" has randomness - that is, you have a list of pure strategies, and you select each one with a given probability whenever you are required to make a decision.
For example, imagine a game with a payoff matrix:
1 0
0 1
for both sides. A pure strategy might be to always go for the first option, while a mixed strategy might be to flip a coin and pick the first iff you get heads.
I don't know what it is you need to know, but from my understanding it's actually not too hard once you understand the terms. Could you give a list of "learning objectives" or something, if they do that at your school? (Or some headings etc from the relevant part of the textbook.)
