Answer:
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
D
Just like heads or tails boy or girl 50 50 chance
1/xyz^3
exponents are subtracted when divided
x^0 is 1
negative exponents are positive in the denominator
(4x^0y^-2z^-3) / (4xy-1)
(4xy^-2z^-3) / (4xy^-1)
x-1y^-1z^-3
16y+2
8x2y=16y
8x1/4=2
