Let X be a random variable with cdf F(x) = { 0, x < 1 (x - 1)/7, 1 <= x < 8 1, x >= 8 } Find P(X = 4).

Step 1
Since X is a continuous random variable (as its cdf is defined for a continuous range of values), the probability of X taking any specific value is always 0. In other words, for any continuous random variable, P(X = x) = 0 for any x. Show more…

Let X be a random variable with cdf F(x) = { 0, x < 1; (x - 1)/7, 1 ≤ x < 8; 1, x ≥ 8. Find P(X = 4).

Random variable X has CDF: if -3 < X < 4: Fx(x) = 0.4 if 4 < X < 5: Fx(x) = 0.8 if 5 < X < 7: Fx(x) = 0.2 Find the conditional CDF Fx|x(2) and P(x|x=2).

Given the below cumulative distribution function, find the following probabilities: CDF: F(x) = 0 if x < 4 0.15 if 4 <= x < 5 0.3 if 5 <= x < 7 0.35 if 7 <= x < 9 1 if 9 <= x P(X = 0) = P(X <= 5) = P(X < 7) = P(7 <= X <= 9) = P(4 < X <= 7) = P(4 < X < 9) = P(X >= 5) = P(X > 7) =
