If four digit number is formed using the digit 0 , \(1,2,3\) with no repetition. Then the probability that the number is both even and divisible by 3 is
- A \(\frac{6}{18}\)
- B \(\frac{5}{18}\)
- C \(\frac{11}{18}\)
- D \(\frac{7}{18}\)
Answer & Solution
Correct Answer
(C) \(\frac{11}{18}\)
Step-by-step Solution
Detailed explanation
Total four digit number formed whose last digit is \(0=6\). Total four digit number formed whose last digit is \(2=5\) There is no repetition hence every number is divisible by 3 . Maximum number of four digit formed using these digits \(=18\) \(\therefore\) Required probability…
