If a die is rolled three times, then the probability of getting a larger number on its face than the previous number each time, is
- A \(\frac{15}{216}\)
- B \(\frac{5}{54}\)
- C \(\frac{13}{216}\)
- D \(\frac{1}{18}\)
Answer & Solution
Correct Answer
(B) \(\frac{5}{54}\)
Step-by-step Solution
Detailed explanation
Here, total number of possible out come \[ =6^3=216 \] Now, we can choose any three numbers out of 6 numbers and we can place them in ascending order and we can place them in ascending order in only one way. So, favourable out come \(={ }^6 C_3=20\) Now, required probability…
