8 percent (C)
To find 1% you divide 4.50 by 100, which is 0.045.
Then you have to find what is added on.
4.86-4.50 is .36
Now you divide .36 by 0.045. An easier way to do this is 360 divided by 45. This equals 8.

Probability that nbr1 is a boy is p1 = 6/10.
Probability that nbr2 is a boy, given 5 boys left is 5/9
Probability that nbr3 is a boy given 4 boys left is 4/8
Probability that nbr 4 is a boy given 3 boys left is 3/7
Approximately 0.071 or 7.1%
Let 
and 
. The the probability both events occurring 
.
This shows 
If A and B are independent
Thus, the statement is (B) False.
