Question 977617: 24. Suppose there are five traffic lights that you need to pass while driving from your work to
school. The probabilities that you will stop for these red lights are: 0 red light with
probability 0.05, 1 red light with probability 0.45, 2 red lights with probability 0.30, 3 red
lights with probability 0.12, 4 red lights with probability 0.06, 5 red lights with probability
0.02. The probability that you stop for at least two red lights on a given day
(a) 0.20
(b) 0.30
(c) 0.50
(d) 1.00
25. A survey was conducted to learn about the shopping preference of consumers during
holiday season. Out of 2000 respondents 22% said they would prefer to shop online

that a randomly selected shopper would use at least one method of shopping is
(a) 0.67
(b) 0.82
(c) 0.60
(d) 0.52

30. The probability that a person can get infected with a rare type of blood disorder is
very small. Suppose that a blood test performed on 10,000 people showed that two
persons tested positive that is, a 0.02% chance of getting this type of blood disorder. This
probability measure was calculated using
(a) conditional probability approach.
(b) marginal probability.
(c) relative frequency approach
(d) classical approach.
