sir I have a doubt in last question of houses where P(A/A2)= 7c2/8c3. why is it chosen as 7c2? please elaborate.

if he has to open house then he must have correct master key also so there is no point choosing that , it has to be there so he has to choose 2 keys out of 7 wrong master keys , while denominator we will have all 8 master keys as we need to take all cases .
