P(x5)

Short Answer

Expert verified

The necessary probability is P(x5)=0.15.

Step by step solution

01

Given Information

To figure out the probability P(x5)from the table using the data provided is used.

A business needs to assess its attrition rate, or the length of time new employees stay with the organization. They've developed the following probability distribution over time.

02

Concept used:

Let's defineXthe number of years a new recruit will stay with the company P(X)and the likelihood that a new hire will stay with the company X years.

The probability is calculated as the sum of the respective probabilities of each occurrence, according to the properties of discrete distribution.

03

Calculation

Using the distribution P(X) ,we can calculate the probability P(x5)as:

P(x5)=P(x=5)+P(x=6)

=0.10+0.0=0.15

04

Step 4:Conclusion:

As a result, the required level of probability is:

P(x5)=0.15
