The probability of getting a sum of $3$,$5$,or $11$ when throwing two dice is:

Two dice are thrown. The events $A, B$ and $C$ are as follows:
$A:$ getting an even number on the first die.
$B:$ getting an odd number on the first die.
$C:$ getting the sum of the numbers on the dice $\leq 5$.
Describe the events $A$ and $B$.

Three houses are available in a locality. Three persons apply for the houses. Each applies for one house without consulting others. The probability that all the three persons apply for the same house is

Two fair dice are rolled. The probability of the sum of digits on their faces being greater than or equal to $10$ is

$A, B, C$ are aiming to shoot a balloon. $A$ will succeed $4$ times out of $6$ attempts. The chance of $B$ to shoot the balloon is $3$ out of $5$ and that of $C$ is $2$ out of $3$. If the three aim to shoot the balloon simultaneously,then the probability that at least two of them hit the balloon is

In the following experiment,specify the appropriate sample space: $A$ person is noting down the number of accidents along a busy highway during a year.
