suresh The probability that a randomly chosen person from a line of 100 people is standing before Aviva or after Naomi can be calculated using the total number of people in the line and their positions.
Given a line of 100 people, Aviva is positioned in the line before Naomi. Therefore, the probability of selecting a person before Aviva is the number of people before Aviva divided by the total number of people in the line.
Let's assume Aviva is the 30th person in the line and Naomi is the 60th person in the line. Therefore, the probability of selecting a person before Aviva or after Naomi is:
(Number of people before Aviva + Number of people after Naomi) / Total number of people
= (30 + 40) / 100 = 70 / 100 = 0.70
Thus, the probability that a randomly chosen person from a line of 100 people is standing before Aviva or after Naomi is 0.70 or 70%.
