You’ll get the answer using Bayes theorem: There will be 3 cases.
  1. Both cards lost are diamond
  2. One of them is diamond
  3. None is diamond ..      (_{2}^{2}\textrm{C}/_{50}^{2}\textrm{C})/ (_{2}^{2}\textrm{C}/_{50}^{2}\textrm{C})+(_{3}^{2}\textrm{C}/_{50}^{2}\textrm{C}) +(_{4}^{2}\textrm{C}/_{50}^{2}\textrm{C}) =1/10
