**Learning Theory** The time *t* (in hours) required for a new employee to learn to successfully operate a machine in a manufacturing process is described by the probability density function

Find the probability that a new employee will learn to operate the machine (a) in less than 3 hours and (b) in more than 4 hours but less than 8 hours.

**(a)**

To determine

**To calculate:** The probability if a new employee is learning to operate the machine in less than *t*(in hours) represents the time required for a new employee to operate the machine successfully.

Explanation

**Given Information:**

The probability density function is represented by, *t*(in hours) represents the time required for a new employee to operate the machine successfully.

**Formula used:**

If *f* is function of a continuous random variable *t*, then the probability that *t* lies in the interval

**Calculation:**

Consider the provided probability density function,

Since, a new employee is learning to operate the machine in less than

The interval in which probability lies is

Now, apply the formula of probability

Substitute the values 0 for *c*, 3 for *d* and

First solve the integral

Let

Now, substitute the above values in the integral

Therefore,

Substitute

**(b)**

To determine

**To calculate:** The probability if a new employee is learning to operate the machine in more than *t*(in hours) represents the time required for a new employee to operate the machine successfully.
