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)
