MCQ
The probabilities of a problem being solved by two students are $\frac{1}{2},\frac{1}{3}$. Then the probability of the problem being solved is
- ✓$\frac{2}{3}$
- B$\frac{4}{3}$
- C$\frac{1}{3}$
- D$1$
$= \left( {1 - \frac{1}{2}} \right)\,\left( {1 - \frac{1}{3}} \right) = \frac{1}{3}$ and
probability that the problem is solved $= 1 - \frac{1}{3} = \frac{2}{3}$.
