$A$ coin is tossed $50$ times,in which $23$ times head comes up and $27$ times tail comes up. Calculate the probability for each event.

From the list of telephone numbers of $100$ employees of a factory, the following frequency distribution of their unit place digit (for example, in the number $25828573$, the unit place digit is $3$) is given in the table below:

Unit digit	$0$	$1$	$2$	$3$	$4$	$5$	$6$	$7$	$8$	$9$
Frequency	$8$	$9$	$12$	$15$	$10$	$7$	$12$	$10$	$9$	$8$

Find the probability that a randomly selected employee has a telephone number with unit digit $3$.

$A$ company selected $4000$ households at random and surveyed them to find out a relationship between income level and the number of television sets in a home. The information obtained is listed in the following table:

Monthly income (in Rs)	$0$ Television	$1$ Television	$2$ Televisions	Above $2$ Televisions
$< 10000$	$20$	$80$	$10$	$0$
$10000-14999$	$10$	$240$	$60$	$0$
$15000-19999$	$0$	$380$	$120$	$30$
$20000-24999$	$0$	$520$	$370$	$80$
$25000$ and above	$0$	$1100$	$760$	$220$

Find the probability of a household earning $Rs. 10000 - 14999$ per month and having exactly one television.

The probability that a non-leap year should have $53$ Sundays is ............ (in $/7$)

Out of $700$ women in an area,$280$ are employed. Find the probability that a randomly selected woman from those women is employed.

Two coins are tossed $1000$ times and the outcomes are recorded as below:

Number of heads	$2$	$1$	$0$
Frequency	$200$	$550$	$250$

Based on this information,the probability for at most one head is
