At a fair, $70$ boys, $80$ girls, $20$ men, and $30$ women have come. Find the probability that a person selected at random to be a prize winner is a woman.

When a balanced die is thrown,find the probability of getting an odd number.

$80$ bulbs are selected at random from a lot and their lifetime (in $hrs$) is recorded in the form of a frequency table given below:

Lifetime (in hours)	$300$	$500$	$700$	$900$	$1100$
Frequency	$10$	$12$	$23$	$25$	$10$

One bulb is selected at random from the lot. The probability that its lifetime is $1150$ hours is:

$A$ box contains $100$ cards marked with numbers $1$ to $100$. If one card is drawn at random from the box,find the probability that the number on the card is: $(1)$ a multiple of $7$,$(2)$ a number smaller than $30$,$(3)$ a prime number.

$A$ 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:

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 at least one defective part.
