Question

Exercise 48 If we throw a fair coin 10,000 times, what is the probability that it lands on “tail” at least 5,500 times?

(i) Write down the exact probability in sum notation.

(ii) Estimate the probability with the Chebyshev inequality.

(iii) Estimate the probability with the Poisson‐Approximation.

(iv) Estimate die probability with the normal distribution.

Exercise 49 Let X ∼ NegBinom(900, 1/4 ). Estimate the probability P(X ≥ 3000)

(i) with the Markov inequality,

(ii) with the normal distribution.

Hint: Use the fact that a negative binomial random variable can be written as a sum of geometric random variables.

Exercise 50 (i) Let Xn ∼ Poisson(10), n ≥ 1, be independent random variables. Estimate the probability that P(9 ≤ S40 ≤ 12).

(ii) Let Xn ∼ Exp(4), n ≥ 1, be independent random variables. Estimate the probability that P (1/100 * S100 ≥ 1 2).
