<s>[INST] Here's a problem:  A coin is flipped multiple times. After each flip, the result is the number of times the coin comes up heads. For example, if the coin is flipped 3 times and comes up heads on the first 2 flips, the result is 2. 

The probability of getting heads on a coin flip is 0.4.  What is the expected value of a 5 flip game?[/INST]
