A packet contains blue, red and green pens such that the probability of picking a blue pen is 2/9 and probability of picking a green pen is 4/9.
If number of red pens is 15 and if all the pens are numbered starting from 1, 2, 3....so on, then what is the probability of getting one pen numbered as multiple of 7 or 11?
