Five digits numbers are formed using the digits and . What is the probability that has even digits at both the ends?
An explanation for the correct option:
Step 1: Find the number of possible outcomes for a given event.
We have been given the five digits numbers are formed using the digits and .
We need to find the probability that has even digits at both ends.
The five digits numbers are formed using the digits and .
The total number of possible cases would be,
Let event : the five-digit number has even digits at both ends.
The number of ways to form the numbers which have even digits at both the ends would be,
Step 2: Find the required probability.
Using the formula of probability the required probability would be,
Therefore, option (A) is the correct answer.
