A random sample of $1,000$ men was selected and each individual was asked to indicate his age and his favorite sport. The results were as follows.

Age/ Sports	Volleyball	Basket ball	Hockey	Football
Below $20$	$26$	$47$	$41$	$36$
$20-29$	$38$	$84$	$80$	$48$
$30-39$	$72$	$68$	$38$	$22$
$40-49$	$96$	$48$	$30$	$26$
$50$ and above	$134$	$44$	$18$	$4$

If a respondent is selected at random, what is the probability that he is between $20-29$ years old

Table 3

The table given below shows the ages of 75 teachers in a school.

Age (in years)	18 – 29	30 – 39	40 – 49	50 – 59
Number of teachers	3	27	37	8

A teacher from this school is chosen at random. What is the probability that the selected teacher is
(i) 40 or more than 40 years old?
(ii) of an age lying between 30 – 39 years (including both)?
(iii) 18 years or more and 49 years or less?
(iv) 18 years or more old?
(v) above 60 years of age?
Note Here 18 – 29 means 18 or more but less than or equal to 29.
