Consider the sample space Ω-10, 1]. Let P be a probability function such that for any interval [a, b], P([a, b) b- a. In other words, probabilty of any interval is its length. Let us start with Co 10, 1], and at nth step, we define C, by removing an interval of length 1/3° from the middle of each interval in Cn-1. For example, G = [0, 1/3ju [2/3, 11, c2 [0, 1/9] U [2/9, 1/3] U [2/3,7/9] U [8/9,...

2) Consider the sample space of three coin tosses: Ω = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT }. Assuming all elements to be equally likely, we assign P({ωi}) = 1/8, i = 1, 2, 3, 4, 5, 6, 7, 8. Define random variable to capture the second and third outcomes of the toss: X2 = { 0, if second outcome is T; 1, if second outcome is H and X3 = { 0, if third outcome is T;...
