<b>Number of cards divisible by 3=8.</b>

Namely...3,6,9,12,15,18,21,24.

<b>Number of cards divisible by 5=5</b>

Namely...5,10,15,20,25.

As you can see,15 is getting repeated in both the cases.

So,

<b>Total number of favourable outcomes=12</b>

Total Number of cards=25.

Probability=Total number of favourable outcomes/Total

=\boxed{12/25}
