The distribution of the weights of $50$ students in a class is as follows:

Weight (in $kg$)	Number of students
$50-52$	$10$
$52-54$	$12$
$54-56$	$13$
$56-58$	$9$
$58-60$	$6$

Find the probability that a student selected at random weighs $56 \ kg$ or more.

The probability of the event 'the sun rises in the east' is .............

Two dice are thrown simultaneously $500$ times. Each time the sum of two numbers appearing on their tops is noted and recorded as given in the following table:

Sum	Frequency
$2$	$14$
$3$	$30$
$4$	$42$
$5$	$55$
$6$	$72$
$7$	$75$
$8$	$70$
$9$	$53$
$10$	$46$
$11$	$28$
$12$	$15$

If the dice are thrown once more,what is the probability of getting a sum $3\,?$

$A$ 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:

$A$ 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.

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
