For drawing a marble which has blue colour =
After that, we are going to find the propability of the complementary event of drawing a blue marble, which could be calculated by this formula
Apply it now....
P(not blue) = 1 - 0.4 = 0.6
I hope you got
the idea!
I am with you if you faced any difficulties!
