Obtain the probability exactly 6 of the next 30 employees hired, resign during the first year.
The probability exactly 6 of the next 30 employees hired, resign during the first year is obtained below as follows:
Let X denotes the number of employees resign during the first year which follows binomial distribution with the probability of success 0.20 and random sample of 30 employees has been selected. That is, n=30,p=0.20
The required probability is,
Use TI-84 Calculator to obtain the probability value.
- Follows the below instructions to obtain the Press 2nd>DISTR
- Select binompdf
- Enter the trails as 30
- Enter the probability of success as 0.20
- Enter the number of success as 6.
- Click Enter.
From the TI-84 calculator, the probability value is 0.1795.
The probability exactly 6 of the next 30 employees hired, resign during the first year is 0.1795.
