A5-digit code is given to all cashiers at a store to let them log onto the cash register. what is the probability that an employee receives a code with all 5 numbers the same?

The probability that an employee receives a code with all 5 numbers the same is .

Step-by-step explanation:

Consider the provided information.

The numbers which we can use in code is: 0,1,2,3,4,5,6,7,8,9

That means there are 10 numbers which we can use.

The total ways of selecting a 5 digit number with all 5 numbers the same = 10.

The total ways of selecting a 5 digit number is: 10×10×10×10×10=

The required probability is:

Hence, the probability that an employee receives a code with all 5 numbers the same is .

after simplifying it i got: -36.25 as my answer. hope that !
