$A$ game of chance consists of spinning an arrow which comes to rest pointing at one of the numbers $1, 2, 3, \dots, 11, 12$ on a circular disc. All these outcomes are equally likely. Then, the probability that the arrow rests to point at $7$ is ..........

The probability of getting the number $7$ while throwing a balanced die once is ...........

Three balanced coins are tossed simultaneously. Find the probability of receiving at least two heads.

If $P(C) = \frac{2}{5}$,then $P(\bar{C}) = \ldots \ldots \ldots$

$A$ carton contains $100$ trousers of which $73$ are good,$12$ have minor defects and $15$ have major defects. Manu rejects only those trousers which have major defects. One trouser is selected at random from the carton. Then,the probability that the selected trouser is accepted by Manu is $\ldots \ldots \ldots \ldots .$

When a balanced die is rolled,the probability of getting a number greater than $4$ on it is ..........
