Step-by-step explanation:
It is provided that, 74% of households said that they have never purchased organic fruits or vegetables.
(a)
<em>X</em> = the number of households in a random sample of 10 who have never purchased organic fruits or vegetables.
<em>X</em> follows a binomial distribution.
The sample space of <em>X</em> is:
