Answer 1

Answer:

Option D is correct

Step-by-step explanation:

From the question, we have:

$Sack\ 1: B, W$

$Sack\ 2: G, Y$

$Sack\ 3: S, R$

Required

The tree diagram

The selection process is as follows:

$Sack\ 1: B, W$

$Sack\ 1\ and\ Sack\ 2: B (G,Y); W(G,Y)$ -- i.e. we write sack 2 as a subset of 1

$Sack\ 1, 2\ and\ 3: B (G(S,R),Y(S,R)); W(G(S,R),Y(S,R))$ -- i.e. we write sack 3 as a subset of 2

The only tree diagram that illustrates this is: option D
