Which of the following cannot be the probability of an event?
Is the given statement correct or not correct?
If a die is thrown, there are two possible outcomes- an odd number or an even number.
Therefore, the probability of getting an odd number is $\frac{1}{2}$.

Therefore, the probability of getting an odd number is $\frac{1}{2}$.
Is the given statement correct or not correct?
If two coins are tossed simultaneously there are three possible outcomes- two heads, two tails or one of each. Therefore, for each of these outcomes, the probability is $\frac{1}{3}$.

- Two dice, one blue and one grey, are thrown at the same time. Complete the following table:
Event: Sum on $2$ dice $2$ $3$ $4$ $5$ $6$ $7$ $8$ $9$ $10$ $11$ $12$ Probability $\frac{1}{{36}}$ $\frac{5}{{36}}$ $\frac{1}{{36}}$ - A student argues that there are $11$ possible outcomes $2, 3, 4, 5, 6, 7, 8, 9, 10, 11$ and $12$. Therefore, each of them has a probability $\frac{1}{11}$. Do you agree with this argument? Justify your answer.
