Assume that it is equally likely for a child to be born a boy or a girl, and that the Lin family is planning on having three children. List the elements of the event that the Lins have at least one girl. (Use B to represent boy, and G to represent girl. For example, if there are three girls born, it would be represented as GGG).

Answer 1

Answer:

$List = \{GBB; BGB; BBG; GGB; BGG; GBG; GGG\}$

Step-by-step explanation:

Given

$Children = 3$

Required

List all cases of having at least 1 girl

We have:

$B = Boy$

$G = Girl$

For 1 girl, we have:

GBB; BGB; BBG

For 2 girls, we have:

GGB; BGG; GBG

For 3 girls, we have:

GGG

Hence, the list is:

$List = \{GBB; BGB; BBG; GGB; BGG; GBG; GGG\}$
