a couple have 5 children, what is the probability that they are all girls?

Question

anonymous · Answer

$$(1/2)^5 = 1/32$$

anonymous · Answer

1/32 is also the probability of having all boys. Or having any combination of boys and girls. This is because there are 32 possible combinations for boys and girls, each with the same probability.

unless there is a third gender, there are two main genders so the probability first child is girl is 1/2

probability second child is girl too 1/2 x 1/2

third child is girl 1/2 x 1/2 x 1/2

fourth child 1/2 x 1/2 x 1/2 x 1/2

fifth child 1/2 x 1/2 x 1/2 x 1/2 x 1/2

got it? :D
