A punnet may contain 10, 11, or 12 strawberries. The probability of having 10 strawberries is 2/5 and the probability of having 11 strawberries is 1/2. Each strawberry has a probability 1/10 of being rotten, independently of all the others. What is the expected number of rotten strawberries in a punnet?
