2 boys and 2 girls are in room P and 1 boy 3 girls are in room Q. Write the sample space for the experiment in which a room is selected and then a person.
Given: 2 boys and 2 girls are in room P and 1 boy 3 girls are in room Q.
To Find: Write the sample space for the given experiment.
Explanation: Let us denote two boys and girls in room P as B1 , B2 and G1 , G2 respectively
Let us denote 1 boy and 3 girls in room Q as B3 and G3, G4, G5 respectively.
According to the question,
Sample spaces for room Sp are
Sp={(P, B1), (P, B2), (P, G1), (P, G2)}
And, Sample spaces for room Sq are
Sq={(Q, B3), (Q, G1), (Q, G2), (Q, G3)}
Now, The total sample spaces for the given experiment:
S=
S={(P, B1), (P, B2), (P, G1), (P, G2), (Q, B3), (Q, G1), (Q, G2), (Q, G3)}
Hence, S is the sample space for the given experiment
