The chance of picking a almond cookie the first time:
you have 6 cookies, 3 of them are almond
So the chance of taking an almond cookie is

The second time there are 5 cookies left, 2 of them are almond cookies
The chance of taking an almond cookie is

To know the probability of picking two almond cookies in a row, multiply the changes:

The chance of taking two almond cookies is 1/5
