Question

Form a ‘Road safety commitee’ of two, from 2 boys (B1, B2) and 2 girls(G1, G2). Complete the following activity to write the sample space.
(a) Committee of 2 boys =

b) Committee of 2 girls =

(c) Committee of one boy and one girl =

 ∴  Sample space = {..., ..., ..., ..., ..., ...}

Solution

(a) Committee of 2 boys = B1, B2
(b) Committee of 2 girls = G1, G2
(c) Committee of one boy and one girl = (B1, G1), (B1, G2), (B2, G1), (B2, G2)

 ∴  Sample space = {(B1, B2), (G1, G2), (B1, G1), (B1, G2), (B2, G1), (B2, G2)}
or n(S) = 6
