If an integer n is to be chosen at random from the integers 1 to 96, inclusive, what is the probability that n(n + 1)(n + 2) will be divisible by 8?
Correct Answer: D
Thinking naively, I thought the answer was B
It took me more than 10 min to get to the correct answer. (The answers don't have explanations so I have to figure it out)
Would someone be able to solve this prob in 2~3 min??
Merci beaucoup in advance!
