Answer:
Step-by-step explanation:
Given four digit numbers are to be formed.
∴ The numbers can't be formed starting with zero.
∴ Total numbers formed
Starting with 2=3=6
Starting with 3=3=6
Starting with 5=3=6
∴ total =6+6+6=18
The numbers being divisible with 5,have to end with 0 or 5
∴ Total such numbers =4+4+2=10
∴ Required probability =10/18=5/9
