2 boys and 2 girls are in Room X and 1 boy and 3 girls in Room Y Specify the sample space for the experiment in which a room is selected and then a person
Given:
The two rooms are X and Y.
In room X−2 boys, 2 girls
[B1,B2,G1,G2]
In room Y−1 boy, 3 girls
[B3,G3,G4,G5]
Case1:
When room X is selected, there are four probabilities of members solution
{xB1, xB2, xG1, xG2}
Case 2:
When room Y is selected, there are four probabilities of members solution.
{yB3, yG3, yG4, yG5}
Therefore, Sample space
S={xB1, xB2, xG1, xG2, yB3, yG3, yG4, yG5}
