A dice numbered $1$ to $6$ on its faces is rolled once. Find the probability of getting either an even number or multiple of $\text{'}3\text{'}$ on its top face.

A cubical die numbered from $1 to 6$ is rolled twice. Find the probability of getting the sum of numbers on its faces is $10$.

If $\mathrm{P}\left(\mathrm{A}\right)=\frac{2}{3}$, $\mathrm{P}\left(\overline{ \mathrm{A}} \right)$ is

A game of chance consists of rotating an arrow which comes to rest pointing at one of the numbers $1, 2, 3, 4, 5, 6, 7, 8$ and these are equally possible outcomes.Find the probability that it will point at an odd number.
