A two-digit number is formed using the digits 2, 3 and 5 without repetition. The probability that the number is divisible by 5 is
A. \(\frac{1}{2}\)
B. \(\frac{1}{3}\)
C. \(\frac{2}{3}\)
D. \(\frac{1}{6}\)
A. \(\frac{1}{2}\)
B. \(\frac{1}{3}\)
C. \(\frac{2}{3}\)
D. \(\frac{1}{6}\)
Best answer
Answer: B. \(\frac{1}{3}\)
\(S = \{23, 25, 32, 35, 52, 53\}\), \(n(S) = 6\). Divisible by 5: 25 and 35. \(P = \frac{2}{6} = \frac{1}{3}\).
