Two dice are tossed. What is the probability that the total score is a prime number.
A
\(\frac{5}{12}\)
B
\(\frac{5}{9}\)
C
\(\frac{1}{6}\)
D
\(\frac{1}{3}\)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Total possible outcome = 6 x 6 = 36
Required outcome = 15
∴ Pr(E) = \(\frac{15}{36} = \frac{5}{12}\)
