The sample space of the possible pairs of candies eaten is
{ ( L , L ) , ( L , C ) , ( L , O ) , ( C , L ) , ( C , C ) , ( C , O ) , ( O , L ) , ( O , C ) , ( O , O ) }
<h3>Further explanation</h3>
The probability of an event is defined as the possibility of an event occurring against sample space.

<h2>Permutation ( Arrangement )</h2>
Permutation is the number of ways to arrange objects.

<h2>Combination ( Selection )</h2>
Combination is the number of ways to select objects.

Let us tackle the problem.
<em>Fred has a lemon drop (L), a cherry drop (C), and an orange drop (O).</em>
<em>Ed has a lemon drop (L), a cherry drop (C), and an orange drop (O).</em>
Each takes out one piece from their bag and eats it.
The sample space of possible pairs of candies eaten is as follows:
Fred eats a lemon drop (L) , Ed eats a lemon drop ( L ) → ( L , L )
Fred eats a lemon drop (L) , Ed eats a cheery drop ( C ) → ( L , C )
Fred eats a lemon drop (L) , Ed eats a orange drop ( C ) → ( L , O )
Fred eats a cherry drop (L) , Ed eats a lemon drop ( L ) → ( C , L )
Fred eats a cherry drop (L) , Ed eats a cheery drop ( C ) → ( C , C )
Fred eats a cherry drop (L) , Ed eats a orange drop ( C ) → ( C , O )
Fred eats a orange drop (L) , Ed eats a lemon drop ( L ) → ( O , L )
Fred eats a orange drop (L) , Ed eats a cheery drop ( C ) → ( O , C )
Fred eats a orange drop (L) , Ed eats a orange drop ( C ) → ( O , O )
From the results above, we can conclude that the sample space is:
{ ( L , L ) , ( L , C ) , ( L , O ) , ( C , L ) , ( C , C ) , ( C , O ) , ( O , L ) , ( O , C ) , ( O , O ) }
