$A$ balanced die is rolled twice. Then,the probability that the sum of numbers received in two trials is $12$ or less than $12$ is ...........

If $P(A) = 0.54$,then $P(\overline{A}) = \ldots$

In any situation that has only two possible outcomes,each outcome will have a probability of $\frac{1}{2}$. True or false? Why?

Two balanced dice are rolled simultaneously. Then,the probability that the same number appears on both the dice is ..........

Two balanced dice are rolled. Find the probability that the sum of numbers on two dice is smaller than $7$.

Chits numbered from $1$ to $120$ are put in a box and a chit is drawn randomly from the box. The probability that the chit drawn bears a $3$-digit number is ............
