Estimate the probability More information. The person must arrive during one of these 10 minute windows, and there are 4 of these non-overlapping windows. Discrete Uniform Distribution Binomial Distribution Sections , Special discrete random variable distributions we will cover More information. X has no restriction so we just integrate over the domain for X: We have to be careful about the limits of integration. The phrase additional may seem confusing because we do not know how long the radio has already been alive.

Probability Theory Probability Spaces and Events Consider a random experiment with several possible outcomes. We want to find the probability that the person has to wait longer than 10 minutes. However, consider how difficult it would be to use the binomial. Z b Continuous Random Variables The probability that a continuous random variable, X, has a value between a and b is computed by integrating its probability density function p. To find c, just integrate the double integral using the appropriate limits of integration, set the result equal to and solve for c.
