The 20 second window corresponds to the vehicles turning left from Weston ( Left hand side road with lightest grey shade) .. that is 2200 vehicles.. and the total vehicles are 9200.. so the fraction is 2200/9200 = 11/46

Drivers of SUVs drive much more carefully today than did SUV drivers in the 1980s. An examination of the number of SUV turn-overs per 1,000 vehicles per annum shows a decrease of 20% from the mid 1980s to the early 2000s.

Which of the following, if true, casts the most doubt on the claim that the average SUV driver of the early 2000s drives more carefully than the SUV driver of the 1980s did?

A. The number of SUV's on the streets of the United States today is twice that of the mid 1980s.

B. The number of SUVs on the streets of the United States today is 20% less than it was in the mid 1980s.

C. Extensive studies, showing that American truck drivers drove less carefully in the early 2000s than they used to in the mid 1980s, included a decrease of approximately 20% in the number of turn-overs between the mid 1980s and early 2000s.

D. SUVs were used in the 1980s primarily for off-road driving, whereas today SUVs are used mainly for road driving, which is less prone to tip-overs.

E. A thorough examination of the reasons underlying each accident shows that tip-overs account for only 1/5 of car accidents resulting in serious or mortal wounds.

Radio talk show host Winfra Opry promotes books on her show. Every show begins with Winfra reading the first chapter of a recently published book on air. Every book that was thus promoted became a national bestseller. In addition, Winfra's show pays royalties to the books' authors.

(A) Books that are written by men are less likely to be chosen by Winfra to be promoted on her show.

(B) Books whose first chapters are very long are less suitable for promotion through Winfra's show.

(C) If a book is not promoted by Winfra on her show, its chances of becoming a best seller are lower than those of books promoted in Winfra's show.

(D) The effectiveness of using the services of a public relations office to promote one's book is lower than the effectiveness of promoting a book through Winfra's show.

(E) A recently published book that gains access to a promotional spot on Winfra's show is likely to become a bestseller.

A man uses a biased dice to decide whether to go ahead with a particular course of action. If the dice shows a prime number, he decided to go ahead with the course of action. What is the probability that the man goes ahead with the course of action? (The die is 6-sided with numbered from 1 to 6)

(1) The probability of the dice showing an even number is double the probability of it showing an odd number; all odd numbers are equally likely and all even numbers are also equally likely.
