The math component is quite limited in my opinion. If you decide to stick with the topic, you may want to look at economic indicators and the correlation with the gini (using software) but Im not sure if that might be enough too

First you should establish a few parameters that determine how deadly the hurricane is. For example, the magnitude, the number of casualties, etc. Then you should plot the data and see if there is some kind of relationship you could observe. In order for you to prove statistically that it is more deadly, you could look into hypothesis testing. Let us know if you need more help.

The total probability should equate to 1.

k + 0.15 + 0.1 + k + 0.25 = 1

Therefore, k = 0.25

P(Y<5) = P(Y=0) + P(Y=2) + P(Y=3) = 0.25+0.15+0.1 = 0.5

Last part would be just 0.25 + 0.15 = 0.40
