The first part of what I am supposed to find is the discrete probability distribution. For this part, I have to look at Australia, Ireland, the Netherlands, New Zealand, and Switzerland.

The second part of what I am supposed to find is the mean, standard deviation, and expected values. I also have to explain how and why expected values is used. For this part, I have to look at Australia, Ireland, the Netherlands, New Zealand, and Switzerland.

The last part of what I am supposed to find is the binomial distribution. For this part, I am just supposed to look at New Zealand.
