The digits 1,2,3,4,5,6 are arranged to form a 6digit number.What is the probability that the number formed is divisible by 4?

The last two digits will need to be divisible by 4.
That means we may have
12,16
24
32,36
44
52,56
64
Or, 9 possible 2digit endings
Since there are 6*5 = 30 total endings, there is a 30% chance that the number is divisible by 4.
