Understanding Uniform Distribution and Probability

This video tutorial explains how to determine probabilities involving a uniform distribution. It provides two examples: one for Worker 1, whose task completion time is uniformly distributed between 10 and 16 minutes, and another for Worker 2, with a distribution between 11 and 16 minutes. The video demonstrates two methods for calculating probabilities: using a fraction bar and calculating the area of a rectangle. The tutorial also explains how to express probabilities as simplified fractions and decimals.

What is the range of time for which worker 1's task completion is uniformly distributed?

• 5 to 15 minutes

• 10 to 16 minutes

• 12 to 18 minutes

• 8 to 14 minutes
