Answer #1

Ans:

(a) Estimate(S4) = 3/5 = 0.6

A table of Sˆ(t):
Values of t Sˆ(t)  
t < 1 5/5=1.000
1 ≤ t < 2 4/5=0.80
2 ≤ t < 3 4/5=0.80
3 ≤ t < 4 4/5=0.80
4 ≤ t < 5 3/5=0.60
5 ≤ t < 8 2/5=0.40
8 ≤ t < 11

Use a Markov chain to compute P(A). Hint: Try using the following three states for your Markov chain: State 0: HT has not appeared yet and cannot appear in the next flip; State 1: HT has not appeared yet, but could appear in the...
