i can swear that the problem is like that, i think the problems are designed by the profesor, can't find it in the internet, so its very weird just gives two data as you can see above and 4 questions i can't put the questions in this way a) probability of lie given the detector shows positive...

Of a and...

hi, i did this in pairs because i needed to know how much pairs of mens are there, and how much pairs of woman as well, so i know that there is a diference between the two positions to be voted, so should i just do a permutation of 7 to 1 to found the b? i don't get very well. for the second...
