$A$ 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 so obtained is listed in the following table:

Monthly income (in Rs)	$0$ Televisions	$1$ 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	$0$	$1100$	$760$	$220$

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 $6$?

$A$ card is drawn at random from a well-shuffled pack of $52$ cards. Find the probability of that card being a queen.
