a urn contain 25 balls numbered 1 through 25. Two balls are drawn from the urn with replacement
13 odd balls
12 even balls
-------------------------------
find the probability of selecting
a) both are odd numbers::: (13/25)^2
---------
b) one odd and one even no.:: (13*12)/25^2
-----------------
C) atleast odd number::: 1 - (2 even) = 1 - (12/25)^2
