Solution

The correct option is C

23


Since the king comes from a family of two children, the total possibilities are (Boy,Boy),(Boy,Girl),(Girl,Boy),(Girl,Girl)

Since one of the two children is already a king (Boy)

Therefore, sample space =(Boy,Boy),(Boy,Girl),(Girl,Boy)

Favorable outcome =(Boy,Girl),(Girl,Boy)

Therefore probability =23
