Question

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

• A. $\frac{1}{4}$
• B. $\frac{2}{4}$
• C. $\frac{3}{4}$
• D. None of these

Answer 1

The correct option is A $\frac{1}{4}$

P(He is $20-29$ years old) $=\frac{38+84+80+48}{1000}$

$=\frac{250}{1000}=\frac{1}{4}$
