eliminate

d)
0.5

D

Step-by-step explanation:

Just like heads or tails boy or girl 50 50 chance

B) 0.06

Step-by-step explanation:

This will make the fourth child; we want the probability that all 4 children are girls.

The probability of having a girl with each child is independent; this means that having 1 girl does not affect your chances of having another girl.

This means the probabilities can be multiplied:

0.5(0.5)(0.5)(0.5) = 0.0625

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
