"Percent" - For details read the explanation given below.
percentages compare numbers in the numerator to 100 and the ratio that compares a number to 100 is logically called percent.
There is a 50% chance that the first color I see will be green color.
Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, The traffic light on Main Street follows a cycle. It is green for 30 seconds, yellow for 5 seconds, and red for 25 seconds.
∴ The sample space N(S) = 60.
So, The probability that the first color I see is green is P(G) = N(G)/N(S).
= 30/60.
= 1/2.
