Over a period of 15 years, the attrition rate in a company has been observed to be an average 10% every year. find the probability that exactly 5 employees chosen randomly from a team of 40 will quit in the year ahead.

Probability that exactly 5 employees chosen randomly from a team of 40 will quit in the year ahead is 0.165.

Step-by-step explanation:

Since we have given that

Total number of employees = 40

Number of employees are going to quit in the year ahead = 5

Rate of attrition = 10%

We will use "Binomial distribution":

Here, n = 40

x= 5

p = 0.1

q = 1-0.1=0.9

Hence, Probability that exactly 5 employees chosen randomly from a team of 40 will quit in the year ahead is 0.165.
