Many internet apps, services and advertising rely on people clicking on links. Here are some questions relating to whether people will click on a link or not. Assume a basic scenario where the probability of someone clicking a link is 0.019. (This seems to be a generally realistic click-through rate).
For all the questions below, briefly identify what information is given, what approach you are using and why, what you are looking for, and then show the calculations.
You and three of your friends, Mo, Chen and Sam have seen the link.
What is the probability that none of you have clicked on the link?
