Understanding Uniform Distribution

The video tutorial explains how to determine the probability of a random variable x being greater than 7 and less than 10 in a uniform distribution between 6 and 11. It uses a graph to illustrate the probability density function and calculates the probability using two methods: dividing the area into rectangles and using the base times height formula. The tutorial emphasizes understanding the uniform distribution and applying mathematical formulas to solve probability problems.
