Suppose a certain traffic light shows a red light for 50 seconds, a green light for 50 seconds, and a yellow light for 5 seconds. If you look at this light at some randomly selected instant, what is the probability you will see a yellow or green light?

Step-by-step explanation:

Given

Required

Determine the probability of Green or Yellow

First, we need to determine the total time

Next, is to determine the required probability

This is calculated as follows:

-- Approximated

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

i think the answer is true
