A bag has ten marbles in it. Three of them are green, one of them are is red, five of them is red, five of them are yellow, and one of them is blue. If one marble is taken out of the bag randomly, what is the probability that it will neither be green nor red

A. 0.60
B. 1.30
C. 0.30 or 0.10
D. 0.03

It is A because it is asking for which is NOT green or red and the majority is not green or red and is DEFINITELY not B.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
