Question

2 boys and 2 girls are in room X and 1 boy and 3 girls are in room Y.Specify the sample space for the experiment in which a room is selected and then a person.

Answer 1

Let boys be denoted by B_X, B₂, B₃ and girls be G₁, G₂, G₃, G_A, G₅ 

Then the required sample space = S. 

= {XB₁, XB₂, XG, XG₂, YB, YG, YGA, YGS} 

Here B₁, B₁, G₁, G₂ are associated with X and B₃, G_b, G_a, Gs are associated with Y.
