The t-distribution is used to make inferences (such as confidence intervals and hypothesis tests) about a population average when you have a small sample size and you don't know the population's true standard deviation.

Sampling Design is the formal plan and methodology for selecting a subset of individuals, items, or events (a sample) from a larger population. The primary goal is to collect data from this sample

If one event can occur in $m$ ways and a second event can occur independently in $n$ ways, then the total number of ways the two events can occur together is $m \times n$.
