For two weeks, mark recorded the color of the traffic light at the intersection of acorn street and fifth avenue as his bus approached the intersection. he created this frequency table. how many times was the traffic light red?

red: ?
green: 6
yellow: 2
total: 15

Hey there!

If the total amount of times Mark recorded the color of the traffic light is 15, then the number of red lights he recorded would be 15 minus the amount of green and yellow lights. 

15 – 6 – 2 = 7

There was a total of 7 red lights recorded by Mark. 

Hope this helped you out! :-)
