For this problem, the most accurate is to use combinations
Because the order in which it was selected in the components does not matter to us, we use combinations
Then the combinations are 
n represents the amount of things you can choose and choose r from them
You need the probability that the 3 selected components at least one are defective.
That is the same as:
(1 - probability that no component of the selection is defective).
The probability that none of the 3 selected components are defective is:
Where 
is the number of ways to select 3 non-defective components from 117 non-defective components and 
is the number of ways to select 3 components from 120.
So:
Finally, the probability that at least one of the selected components is defective is:
P = 7.4%
Answer:
D. |-3 - (-10)|
Step-by-step explanation:
-2/1 I did this is math class , we’re on this unit to,
Explanation
Saying it’s a negative number because it is pointing in a left word position, you have to go down twice and over once to find the exact point where the line crosses over a point on the graph, and there you will get -2/1
.60×.55=.33 cent mark up to original price
.60+.33=.93 cost per muffin
.6×100=60×.55=93 cost for 100 muffins
93/100= .93 cost per muffin
Answer:
15
Step-by-step explanation:
if you divide 20 by 8, then you get 2.5. multiply that by six, and you get your answer.
