WebProblem Solutions – Chapter 4 Problem 4.1.1 Solution (a) The probability P[X ≤ 2,Y≤ 3] can be found be evaluating the joint CDF F X,Y(x,y)at x =2andy = 3. This yields P [X ≤ 2,Y≤ 3] = F X,Y (2,3) = (1−e−2)(1−e−3)(1) (b) To find the marginal CDF of X, F X(x), we simply evaluate the joint CDF at y = ∞. F X (x)=F X,Y (x,∞)= 1−e−x x ≥ 0 0 otherwise
WebMar 6, 2024 · Explanation: The standard notation is to use a lower case letter to represent an actual event, and an upper case letter for the Random Variable used to measure the probability of the event occurring. Thus the correct table would be: And then; P (X > 5) = P (X = 6 or X = 7 or X = 8) = P (X = 6) +P (X = 7) + P (X = 8) = 0.2 +0.1 +0.5 = 0.8
