Of 24 employees at a local supermarket, 13 work as cashiers and 11 stock shelves. if 4 employees are selected at random to work overtime, determine the probability that all 4 are cashiers.

The required probability is,

Step-by-step explanation:

Of 24 employees at a local supermarket, 13 work as cashiers  and 11 stock shelves. If 4 employees are selected at random to work overtime, then

P( all 4 are cashiers) =

Step-by-step explanation:

Given : Total number of employees = 24

Number of cashiers = 13

Number of stock shelves = 11

Number of ways to choose 4 out of 24 people =  (Total outcomes)

Number of ways to select 4 out of 13 cashiers = (Favorable outcomes)

According to the definition of probability :

Then , the probability that all selected 4  employees are cashiers. :-

Hence, the required probability is .
