#### Applying Normal Distributions in Real Life

- Normal distribution is used to model many things in real life as it is a very reasonable model. Therefore, knowing how to apply the knowledge of normal distributions in real life problems is important.

Example

**The time taken to complete a logical reasoning task is normally distributed with a mean of 55 seconds and a standard deviation of 8 seconds. Keeping the answer as accurate to 4 d.p.,**

**a) Find the probability that that a randomly chosen person will take less than 50 seconds to complete the task.**
