$A$ die is thrown $1000$ times and the outcomes were recorded as follows:
Outcome $1$ $2$ $3$ $4$ $5$ $6$ Frequency $180$ $150$ $160$ $170$ $150$ $190$
If the die is thrown once more,then the probability that it shows $5$ is:
| Outcome | $1$ | $2$ | $3$ | $4$ | $5$ | $6$ |
| Frequency | $180$ | $150$ | $160$ | $170$ | $150$ | $190$ |
If the die is thrown once more,then the probability that it shows $5$ is:
- A$\frac{3}{20}$
- B$\frac{9}{50}$
- C$\frac{4}{25}$
- D$\frac{7}{25}$
