Dear folks, please review where is the mistake with the following probability problem:
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?
answ. said 5/8 but i got 1/8. where is the mistake?
n(n+1)(n+2) is consecutive integer and divisible by 8 is 8,16,24,32,40,48........96 (multiple number of 8)
thus, from 1 to 96 there are 12 number of 96 (12/96)--->1/8
thx
