Question

There is a traffic light at the intersection of pine street and spruce avenue the traffic light on pine street follows a cycle it is green for 35 seconds,yellow for 10 seconds and red for 15 seconds as you travel along pine and approach the intersection what is the probability that the first color you see is yellow

Answer 1

10/60= 1/6
p(event)= # of ways an event can occur/sample space zice(the number of possible outcomes)

Answer 2

0.167

Explanation:

Green Light = 35 seconds

Yellow Light = 10 seconds

Red Light = 15 seconds

Total second = 60

So, probability that the first color you see is yellow =
`\frac{\text{Yellow light time}}{\text{total time}}`

=
`(10)/(60)`

=
`(1)/(6)`

=
`0.167`

Hence the probability that the first color you see is yellow is 0.167.
