Two dice are thrown simultaneously $500$ times. Each time the sum of two numbers appearing on their tops is noted and recorded as given in the following table:
Sum Frequency $2$ $14$ $3$ $30$ $4$ $42$ $5$ $55$ $6$ $72$ $7$ $75$ $8$ $70$ $9$ $53$ $10$ $46$ $11$ $28$ $12$ $15$
If the dice are thrown once more,what is the probability of getting a sum $3\,?$
| Sum | Frequency |
