Let’s go back to the fi rst example of long and short winters. Suppose there are 1,600 adults of type L, 1,600 of type S, and 1,600 randomizer types. The randomizer types decide at the start of each summer whether to gather enough food for a long winter, and do gather enough with probability 0.4.

Suppose we have the sequence summer, short winter, summer, short winter, summer short winter, summer, long winter, how many of each type will likely survive?
