C. because the decimal is never ending, so it is irrational.
D is the answer that is graphed.
Answer:
#1 is It could be another girl or it could be a boy
#2 is Its could be another boy or it could be a girl.
The diagram should look like this:
BB. BG
GB GG
#4 is 4
#5 is 1
#6 is there is 1/2 a change the baby can be a girl and a 1/2 change the baby can be a boy. For both of them to be girls; it would be 1/4 chance.
To solve this you need to take the answer from the previous iteration.
Iteration 1: The answer is given
a1 = 300
Iteration 2: Solve using the equation. a(n-1) is the answer from the previous iteration. n = the number of the current iteration. So, a(n-1) = 300 and n = 2
a2 = 300/2 = 150
Iteration 3: a(n-1) = 150 and n = 3
a3 = 150/3 = 50
Iteration 4: a(n-1) = 50 and n = 4
a4 = 50/4 = 12.5
Answer: 12.5
