Using the concept of probability and the combination formula, it is found that there is a 0.4444 = 44.44% probability they get to be on the same team.
--------------------
- A probability is the <u>number of desired outcomes divided by the number of total outcomes.</u>
- The order in which the children are chosen is not important, which means that the combination formula is used to find the number of outcomes.
--------------------
<u>Combination formula:
</u>
is the number of different combinations of<u> x objects from a set of n elements</u>, given by the following formula.
--------------------
Finding the number of desired outcomes:
- Andy and Ollie on the same team, plus 3 children from a set of 8.
- Can be on either team, blue or red, so multiplied by 2.
--------------------
Finding the number of total outcomes:
- <u>5 children from a set of 10</u>, thus:
--------------------
The probability is:
0.4444 = 44.44% probability they get to be on the same team.

The surface area is 314.2
The formula of the sphere to find surface area is A = 4•3.14•r^2 , substitute 5 for r, then multiply 5^2, after you get that product then multiply it by 3.14/pi. Once you get that product, multiply that by 4 and you get the final product. Then round to the nearest tenth, which is how you get 314.2
Answer:
-2
Step-by-step explanation:
Slope intercept form is
y = mx + b
Where m is the slope
Parallel lines have the same slope
----------------------------
y = -2x + 5
is in slope intercept form
the slope, m = -2
The slope of the parallel ine will be the same
m = -2
