Probability calculations determine the chance of a specific event occurring. This calculation factors in the number of positive events with respect to the total number of possible results. When you ...

We toss an unbiased coin four times, and choose \(\Omega=\{H,T\}^4\) for our sample space. We write \(X\) for the number of heads in the first three tosses and \(Y\) for the number of heads in the ...
