a) Find the value of ‘*’ and Find the expected category of hurricane to make landfall, E(X). What is the probability that a Category 4 or stronger hurricane will make landfall?Calculate the variance. Table 1 below shows the probability distribution of hurricanes that have made landfall inthe Caribbean. The random variable, X, is the category of the hurricane. Category 1 is theweakest hurricane level while category 5 is the strongest.Table 130.131P(X=x) 0.4120.3440.075*
