Answer:
1/8
Step-by-step explanation:
This is actually pretty easy.
First, you have the sample of the children.
You know that the family with 3 children, can only have the following children:
MMM: all males
MMF: 2 males, 1 female
MFF: 1 male, 2 females
MFM: 2 males, 1 female (different order)
FMM: 1 female, 2 males
FFM: 2 females, 1 male
FMF: 2 females, 1 male
FFF: 3 females
If you count all of these possibilities, we have 8 possible cases of family with the childrens.
In only one of them, we have only females and no males, which is the last one, all 3 females.
Therefore, the probability to select a family with no male, is only 1/8.
Answer:
Step-by-step explanation: 4
Answer:
n=1
Step-by-step explanation:
distribute
-6 times -8n is =48n
-6 times 6 =-36
8 times -4 = -32
8 times n =8n
rewrite equation
48n-36+-32+8n=-12
48n+8n-36-32=-12
56n-68=-12
add 68 on both sides
=56
56n=56
n= 1
