$\frac{3}{5}$
You have the probabilities:$\frac{4}{10}$ and $\frac{5}{10}$.Add the probabilities to find the probability of either of the events occurring. Then, subtract $\frac{x}{y}$ because that is the probability that both events will occur $\frac{4}{10}$ +$\frac{5}{10}$ - $\frac{3}{10}$ $\frac{6}{10}$ -simplify- =$\frac{3}{5}$
