Q75 / 160 · AP EAMCET 2024 (23 May Shift 1) · Mathematics
When two dice are thrown, the probability of getting the sum of the values on them as 10 or 11 is
- A$\frac{7}{36}$
- Correct answerB$\frac{5}{36}$
- C$\frac{5}{18}$
- D$\frac{7}{18}$
Solution
Number of elements in sample space $=6 \times 6=36$
Sum is 10 or $11=(4,6),(5,5),(5,6),(6,4),(6,5)$ $\therefore$ Required probability $=\frac{5}{36}$.
Sum is 10 or $11=(4,6),(5,5),(5,6),(6,4),(6,5)$ $\therefore$ Required probability $=\frac{5}{36}$.
Hence, the correct answer is option: 'B'.
