A husband and wife appear in an interview for two vacancies for same post. The probability of husband getting selected is $\frac{1}{5}$ while the probability of wife getting selected is $\frac{1}{7}$ Then the probability that anyone of them getting selected is
- A. $\frac{11}{35}$
- B. $\frac{12}{35}$
- C. $\frac{10}{35}$
- D. $\frac{34}{35}$
Answer: D. $\frac{34}{35}$
Explanation: The probability of getting anyone selected $=1-\frac{1}{5}\times\frac{1}{7}=\frac{34}{35}$
