Aren't P and Q symmetry upon y-axis? Nope they are not symmetric. We should not rely on the GMAT to provide us figures drawn to scale (implying you cannot use a protractor to measure their diagrams :D ) http://i.imgur.com/7CMYPXe.png In the figure shown, points P and Q lie on the circle with center...

How if we only try find the probability that 2 of the last 4 bombs do not blast? The two bombs dont blast implying that 20% are always defective. Since in our case first six bombs do blast these 20% defective ones fall in the last 4. So imo we can use the P(non defective) probability for first six....

positive difference between a and b = distance between a and b on the number line OR absolute value of |a - b|
If you knew which number was bigger then you would not require the mod sign (if a > b then a - b is the positive difference)
In fact differences are always positive
