For the answer to the question above, the probability that Eduardo pulls out a girl the first time is 16/26 (26 - 10 = 16) which means that pulling out a girl a second time would be 15/25. To find out the probability of both, you have to multiply the fractions together. So (16 × 15)/(25 × 26) which is 240/650. You can simplify this to 24/65, and I believe that is the furthest you can simplify it, which means that the answer is 24/65, I hope this helps!
