Answer:
a.0.0078125
b. 0.1640625
c. 0.0078125
d. 0.0078125
Step-by-step explanation:
To solve this question we can use the binomial probability function:

where
- n is the number of trials in this case the number of children
- k is the number of successes, we can think it as the number of boys
- p is the probability that is a boy
- q is the probability that is a girl,
In this case case p=q
Then
(a) 
(b) 
(c)
(d) 
(a), (c) and (d) are equal as a result of equal probability of giving birth to a boy or a girl. (b) is different because it takes into account the different orders that births can occur

Step-by-step explanation:
Given that:
Initial number of bales of hay = 1041 bales
After stacking more bales in the barn:
Total number of bales after stacking = 2,358 bales
Equation for scenario b
Initial bales + added bales = total number of bales after stacking
Let added bales = b
1,041 + b = 2,357
Added bales = Newly stacked bales:
1041 + b = 2,357
b = 2357 - 1041
b = 1,316
The stacked bales of hay stacked to join the initial is. 1,316 bales

Answer:
Measure of Data Dispersion
Step-by-step explanation:
Standard deviation is used to show the variation and dispersion in a group of data. It shows how separated the data's are to each other and how each data can be related to the other.
A normal data distribution are those group of data, that are distributed in a wide range. The standard deviation helps to to measure how they are been spread out.
Standard deviation does not measure the shape, quality, and center of data. This are measured with graphs, range, mean and median.
