Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have 
ways to to choose 4 good components from 8.
We have 
ways to choose 4 components from a total of 9.
If all function properly then none is bad, we 
way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444

If you have an app like Desmos, you can just input that. If not, you would subtract X from both sides to get 2y=-x-2. Then, you would divide by 2 on both sides to get y=-1/2x-1. You can input that into Desmos or a graphing calculator. Please mark me brainliest, but its fine if you don’t want to. Have a good day!
