Questions 11-15 will be based on the following.

On any given day, there are messages on our discussion board and there are probabilities associated with a number of messages being read.

On a particular day, there are 24 messages. Let x be the number of messages read, and p(x) the probability that those number of messages get read, so for example, if x=3 and p(x)=0.005, then on that particular day, the probability of 3 messages getting read is 0.005.

Here are theprobabilities.

Please choose the best answer.
