The set S consists of 5 numbers: {1,2,3,4,5}

The set S consists of 5 numbers: {1,2,3,4,5}. If all possible subsets including the null set are created and one subset is chosen at random, what is the probability that the subset has 4 or 5 as its largest number?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
