Question 3 - Stage 1

You are going to roll five fair six-sided dice with sides labelled 1 to 6.

Your aim is to insert your five scores into the boxes below to create a 5-digit number (i.e. a number in base 10 between 11111 and 66666) that is divisible by 25.

 What is the probability (to 3d.p.) that this is possible?
