5 Must Know Facts For Your Next Test

  1. Probability can be calculated using improper integrals when dealing with continuous random variables.
  2. The probability density function (PDF) must integrate to 1 over its entire range.
  3. The cumulative distribution function (CDF) gives the probability that a random variable is less than or equal to a certain value.
  4. In some cases, improper integrals are used to find the expected value (mean) or variance of a probability distribution.
  5. Understanding convergence of improper integrals is crucial for evaluating probabilities in unbounded intervals.
