... 1. A fair coin is tossed 10 times. (i) Find the probability of getting exactly three heads. (ii) Find the probability of getting 3 or fewer heads. SOLUTION: We set it up by counting how many things are in the sample space, then count how many ways of getting the three heads. For each of the 10 coin ...

Conditional Probability
... This is an example of a conditional probability: we are interested in the probability that a person has the condition (event A) given that he/she tests positive (event B). Let’s write this as Pr[A|B]. How should we define Pr[A|B]? Well, since event B is guaranteed to happen, we should look not at th ...
