The probability table is shown below.
A Poisson distribution can be used to approximate the model of the number of hurricanes each season.
Step-by-step explanation:
(a)
The formula to compute the probability of an event <em>E</em> is:
Use this formula to compute the probabilities of 0 - 8 hurricanes each season.
The table for the probabilities is shown below.
(b)
Compute the mean number of hurricanes per season as follows:
If the variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 7.56 then the probability function is:
Compute the probability of <em>X</em> = 0 as follows:
Compute the probability of <em>X</em> = 1 as follows:
Compute the probabilities for the rest of the values of <em>X</em> in the similar way.
The probabilities are shown in the table.
On comparing the two probability tables, it can be seen that the Poisson distribution can be used to approximate the distribution of the number of hurricanes each season. This is because for every value of <em>X</em> the Poisson probability is approximately equal to the empirical probability.

^7√(-4)^2 or 1.48 I hope it helps
Charles Lindbergh made the first solo airplane flight from New York to paris.
His flight covered about 3 610 miles in 33.5 hours.
Let’s find the Unit Rate for this given data:
=> 3 610 miles is the total distance
=> 33.5 hours is the time
Let’s divide the distance by time to get the answer
=> 3 610 / 33.5
=> 107.8 miles per hour – this is the unit rate that Charles travelled in plane from New York to Paris
