I Visited a Beautiful Flower Garden Yesterday and Counted Exactly

Short Answer

I visited a beautiful flower garden yesterday and counted exactly 60 flowers. Each flower was either white or purple, and the flowers were not all the same color. My friend made the following observation: No matter which two flowers you might have picked, at least one was bound to be white. From this can you determine how many were white and how many were purple?
