The maker of a computer chess game claims the game can beat

Question

The maker of a computer chess game claims the game can beat a human chess champion 35% of the time. A human chess champion plays ten games against the computer. Assuming the manufacturers claim is true, you are interested in the probability that the human chess champion wins a majority of the games.

Pick the equation most appropriate to deal with the problem above.

1. z= x-μσ
2. x = μ + zσ
3. z= x-μ σ/n
4. p(x)=(nCx)px(1- p)n-x

NONE OF THE ABOVE

Need help with how to figure this one out please and thank you!
