The cycle of a traffic light at an intersection of two streets is 35 seconds green, 5 seconds yellow, and 10 seconds red. if you reach the intersection at a random time, what is the probability that the light is red?

The probability of finding the light red is 0.20 (20%).

Step-by-step explanation:

We have 3 options. The number of times we can get the light is 10.

To get the probability  equally likely of having a traffic light red we use the following formula

P=# of possibilities that meet the condition / #of equally likely possibilities.

In this case, the number of equally likely possibilities is 50 (35 seconds green, 5 seconds yellow, and 10 seconds red).

P(red)=10/50=0.20

can you rephrase the question ? it is unclear : -)
