Answer:
0.292
Step-by-step explanation:
When we select the first widget, there are 20 good widgets from 25 total.
When we select the second widget, there are 19 good widgets from 24 total.
So on and so forth.
So the probability is:
P = (20/25) (19/24) (18/23) (17/22) (16/21)
P = 0.292
Alternatively, we can calculate this using combinations.
We are selecting 5 widgets from a total of 25. ₂₅C₅
From the 5 defective widgets, we want to select 0. ₅C₀
From the 20 non-defective widgets, we want to select 5. ₂₀C₅
So the probability is:
P = (₅C₀ ₂₀C₅) / ₂₅C₅
P = 0.292
The expressions that represent the total number of berries in the Berry Blast smoothies that Luther made today is 3 + b = 20
<h3>How to write system of equations</h3>
Let the number of strawberries be x
Let the number of b berries be y
If at work today, he made 20 Berry Blast smoothies, then;
x + y = 20
SInce x = 3 and y = b, then;
3 + b = 20
The expressions that represent the total number of berries in the Berry Blast smoothies that Luther made today is 3 + b = 20

Hello,
cos 160°=-q
cos 20°=-cos 160°=q
sin 20°=√(1-q²)=sin 160°
tan -20°=tan 160=√(1-q²)/-q
cos 70°=sin 20°=√(1-q²)
