*(probability) 4 traffic lights A, B, C, D have red light. If the probabilities that the red lights of A, B, C, and D hold are 0.5, 0.6, 0.7, and 0.8, respectively, what is the probability that a car passes by A and D and stops B and C, approximately?
A. 4% B. 7% C. 10% D. 15% E. 40%


Looking at the screenshot you sent, it looks like the question is exactly as you have written. I would suggest you to ignore this source since it seems to be very sub-standard.

As for this question, if the red light holds, the car stops. If it changes, the car passes through.

Probability that A and D turn while B and C hold = 0.5 * 0.6 * 0.7 * 0.2 = 4.2%

Hi Karishma,
(geometry) Two people run the circle with 10 rounds, one runs in the inside and the other runs in the outside. When the difference between the inside and the outside is 15 feet, what is the difference of between two people's distance after running 10 rounds, approximately?

I don't understand this question. It seems to say that one person runs 10 rounds outside and another person runs 10 rounds inside. If the difference in the circumference is 15 feet, the one outside will run 10*15 feet extra. If the difference of 15 feet is between radii or diameter, it will be different. The question needs to clarify properly.

Hi VeritasKarishma, Can you please tell me most important quant topics I need to cover. I have a booked GMAT next week. I thought I was good at quant so I concentrated mostly on my verbal ability. Now my mock score is only 45. My target is 50/51. I am ready to put in 100 hours this week.Thanks!

Number Properties, Algebra and Geometry are the most important topics. Also, ensure that you understand the Data Sufficiency format really well. What is sufficiency, how to avoid common traps etc.
