Step 1: Le couple a exactement 1 enfant si le premier est un garçon.

Formule : P(1enfant)=P(1er=garc\con)P(1 enfant) = P(1er = garçon).

Substitution : P(1er=garc\con)=12P(1er = garçon) = \frac{1}{2}.

Simplification : P=12P = \frac{1}{2}.

12\boxed{\dfrac{1}{2}}

Step 1: Le couple a exactement 2 enfants si le premier est fille et le deuxième garçon.

Formule : P(2enfants)=P(1er=fille)×P(2e=garc\con)P(2 enfants) = P(1er = fille) \times P(2e = garçon).

Substitution : $P = \frac{1}{2} \times \frac{1}{2} = \frac{
