Suppose there are 1600 individuals who always gather enough food for a long winter, 1600 individuals who always gather enough food for only a short winter, and 1600 individuals who choose with 50% probability, each year, to gather enough food for a long winter. If a winter turns out to be short, then those who prepared for a long winter have a 50% probability of surviving the year, while those who only prepared for a short winter have a 75% probability of surviving, because they had the advantage of spending less time on preparation. But, if a winter turns out to be long, then those who prepared for a long winter have a 50% probability of surviving the year, while those who only prepared for a short winter will denitely not survive. How many individuals of each type will survive one short winter followed by one long winter? Answer in at most three sentences
