Best ResponseYou've already chosen the best response.1the probability that you decide to buy a ticket and it loses is \(\frac{1p}{2}\) viewing this as bernoulli trials (independent repeated experiments with only two outcome) the the formula is \[P(x=k)=\dbinom{n}{k}p^k(1p)^{nk}\] but in this case \[p=\frac{1p}{2}\] and therefore \[1p=1\frac{1p}{2}=\frac{1+p}{2}\]

Best ResponseYou've already chosen the best response.1i guess what i wrote is silly, i should have made the first \(p\) a \(p^*\) or some other variable
