On tossing two coins simultaneously,find the probability of getting no tail.

When a balanced die is thrown,the probability of getting $3$ is .........

Bulbs are packed in cartons,each containing $40$ bulbs. Seven hundred cartons were examined for defective bulbs,and the results are given in the following table:

Number of defective bulbs	$0$	$1$	$2$	$3$	$4$	$5$	$6$	More than $6$
Frequency	$400$	$180$	$48$	$41$	$18$	$8$	$3$	$2$

One carton was selected at random. What is the probability that it has defective bulbs from $2$ to $6$?

$A$ die is thrown $1000$ times and the outcomes were recorded as follows:

Outcome	$1$	$2$	$3$	$4$	$5$	$6$
Frequency	$180$	$150$	$160$	$170$	$150$	$190$

If the die is thrown once more,then the probability that it shows $5$ is:

As the number of tosses of a coin increases,the ratio of the number of heads to the total number of tosses will be $\frac{1}{2}$. Is it correct? If not,write the correct one.
