The probability that neither of them can get the math book is (3/5) 2 = 9/25.

The probability that they get the math book is (2/5) 2 = 4/25.

In addition to the above two situations, the rest is that one person must have got the math book, so the probability that one of the two people will get the book is:

1-9/25-4/25= 12/25
