You decided to buy 2 birds from a pet shop and went to a pet shop for it. There are 12 budgerigars at the pet shop and you want a male and a female for your home. You cannot distinguish the gender of birds by just looking at them. So you ask for 2 birds with different genders to the shopkeeper and the shopkeeper is actually a good math teacher in a school and tells you that
I have 6 male and 6 female budgerigars in my shop. You can choose as many birds as you want among them, every time I will tell you how many males there are among the birds you choose.
So tell me at least how many times I need to tell you how many males there are in the chosen group of birds to guarantee to find a male and a female budgerigar? I will give you the birds for free if you answer correctly!
