... helpful at all. We didn’t gain anything by using Markov’s inequality in this case. 4b. Now we use the Central Limit Theorem to approximate P (X ≥ 15). We already noted that X has mean 20. Also, each Xi is Poisson with λ = 1,√so each Xi has variance 1, so the variance of X is also 20, and X has stand ...

H = 5 and T = 5 is the most symmetric outcome, and thus most ‘likely’. ‘Less symmetric’ outcomes are ‘less likely’. ‘Fairness’, i.e., symmetry, s ...
