The question carries an error! There are five nails and half of 5 is 2.5. It is now a meaningless assertion to say 2.5 nails (question says half of the nails and half of the nuts are rusted) are rusted. Kindly rectify the mistake and forward it once again.

P(rusted) = 8/16 P(nail) = 6/16 P(rusted and nail) = 3/16 P(A intersection B) = 8/16 + 6/16 - 3/16;

If you want you can consider the other half nail as 3rd rusty nail and proceed if you really want to consider and solve the question...!!!

P(rusted) = 8/16 P(nail) = 6/16 P(rusted and nail) = 3/16 P(A intersection B) = 8/16 + 6/16 - 3/16 =11/16

I think, half of the nails = 5/2 which is not appropriate, because counting nails cannot be a fraction
