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

Out of $30$ days, the forecast predicted by the weather department proved to be true on $20$ days. If one day is chosen at random from these $30$ days, what is the probability that the forecast proved to be false?

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

Over the past $200$ working days,the number of defective parts produced by a machine is given in the following table:

Number of defective parts	$0$	$1$	$2$	$3$	$4$	$5$	$6$	$7$	$8$	$9$	$10$	$11$	$12$	$13$
Days	$50$	$32$	$22$	$18$	$12$	$12$	$10$	$10$	$10$	$8$	$6$	$6$	$2$	$2$

Determine the probability that tomorrow's output will have no defective part.

$A$ recent survey found that the ages of workers in a factory is distributed as follows:

Age (in years)	$20-29$	$30-39$	$40-49$	$50-59$	$60$ and above
Number of workers	$38$	$27$	$86$	$46$	$3$

If a person is selected at random,find the probability that the person is under $60$ but over $39$ years.

$A$ balanced die is tossed once. The probability of getting number $6$ on the die is ..............
