At a traffic light you have 3 minutes of red light and 1 minute of green light. what is the probability of getting a red light?a green light?

The chance is 3/5 that the light will be green.

Added together the total seconds for the traffic light to complete the cycle is 120 (38+72 (1 min and 12 sec) +10.

And the green light proportion is: 72/120

We simplify by dividing by 12, which is a factor and we get: 6/10 that simplifies to 3/5.

Hope this helps!

Step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
