The probability of an event A is 1/5. The probability of B is 1/3 . The probability both A and B is 1/15. What is the probability of either event A or B or both
- \( \frac{2}{15} \)
- \( \frac{3}{4} \)
-
\( \frac{9}{15} \)
- \( \frac{1}{15} \)
The correct answer is: C
Explanation
In probability, or = +
Prob( A or B or Both ) = \(\frac{1}{3} + \frac{1}{5} + \frac{1}{15}\) = \(\frac{5+ 3 + 1}{15}\) = \(\frac{9}{15}\) = \(\frac{3}{5}\)
