The following is the probability mass function for a discrete random variable X,
$ P(x) = \frac{x}{100}; X = 10, 20, 30, 40 $
Determine the CDF at X=30, i.e., F(30) | Financial Risk Manager Part 1 Quiz - LeetQuiz
Financial Risk Manager Part 1
Explanation:
The cumulative distribution function (cdf) F(x) defines the probability of a random variable X, and assumes a value equal to or less than a specified value, x. As such:
F(30)=P(X≤30)=P(X=10)+P(X=20)+P(X=30)=10010+10020+10030=0.6 or 60%
