\(\frac{8}{11}\)
\(\frac{3}{11}\)
\(\frac{4}{11}\)
\(\frac{5}{11}\)
Correct answer is B
Total numbers from 40 to 50 inclusive = 11 (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50).
Prime numbers between 40 and 50 (inclusive) are 41, 43, and 47.
There are 3 prime numbers in this range.
therefore, Pr(prime numbers) = \(\frac{3}{11}\)
