Question

A box contains a red marble and a blue marble. A second box contains a red marble, ablue marble, a yellow marble, and a green marble. One marble is drawn from each box, Specify the event that at least 1 marble is blue.Answer choicesA. (R, B); [B, B) (B, R]; [B, Y): [B, G]B. [R, B): (B, Y); (B, G)C. (R, B); (R, Y): (R, G); [B,B); (B, R): (B,Y): (B, G)D. (R,B); (B,R); (B,Y); (B,G)

Answer 1

To determine the event of getting at least one blue marble we need to construct all the possibilities where one blue marble is picked, we can find this using a tree diagram:

From it we can construct the following possibilities:

• Red-Blue

,

• Blue-Red

,

• Blue-Blue

,

• Blue-Yellow

,

• Blue-Green

This can be written as:

{R,B}; {B,R}; {B,B}; {B,Y}; {B,G}

Therefore, the answer is the first option.
