1:4. 16 is 25% of 64, or 1/4, this translates to 1:4 in ratio form.
P(pirate hits) = 1/4
P(captain misses) = 1 - 3/4 = 1/4
We assume these events are independent, so their joint probability is the product of their individual probabilities:
P(pirate hits & captain misses) = (1/4)·(1/4) = 1/16
When a finite number of samples are drawn from a larger population, the sample mean of that sample, while usually close to the population mean, is not the same thing. A population mean, on the other hand, is a description of pretty much ALL of whatever is being examined.
Example of population: Everyone in the USA
Example of a sample: One person, chosen at random, from each of the 50 states
