Total 5 digit numbers formed by the given digits=5×5!=600
For a number to be divisible by 5, the last digit should be 0 or 5
Case 1: Numbers ending with 0
_ _ _ _ 0
The other places can be filled in 5 * 4 * 3 * 2 ways = 120
Case 2: Numbers ending with 5
_ _ _ _ 5
The other places can be filled in 4 * 4 * 3 * 2 = 96
Total favorable = 96 + 120 = 216
Required Probability = 216 / 600 = 0.36
