Question

A small community organization consists of 20 families, of which 4 have one child,8 have two children, 5 have three children, 2 have four children, and 1 has fivechildren. If one of these families is chosen at random, what is the probability it has`children,`= 1,2,3,4,5?

Answer 1

Answer and Step-by-step explanation:

According to the situation, The probabilities for each one is given below:

As there are 20 families

So the probabilities for each one is

For four families have one child is

$= \frac{4}{20}\\\\ = \frac{1}{5}$

For eight families have two children is

$= \frac{8}{20}\\\\ = \frac{2}{5}$

For five families have three children is

$= \frac{5}{20}\\\\ = \frac{1}{4}$

For two families have four children is

$= \frac{2}{20}\\\\ = \frac{1}{10}$

For one family have five children is

$= \frac{1}{20}$
