Airline Fatalities One study showed that in a certain year, airline fatalities occur at the rate of 0.011 deaths per 100 million

Answer:

$P(X = 0) = 0.9891$

Step-by-step explanation:

Given

$\lambda = 0.011$

Required [This completes the question]

The probability of exactly 0 deaths

This probability follows a Poisson distribution, and it is given by:

$P(X = x) = \frac{e^{-\lambda}\lambda^{x}}{x!}$

For 0 deaths;

$x = 0$

So, the expression becomes

$P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{0!}$

$P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{1}$

$P(X = 0) = \frac{e^{-\lambda}*1}{1}$

$P(X = 0) = e^{-\lambda}$

Substitute 0.011 for $\lambda$

$P(X = 0) = e^{-0.011}$

$P(X = 0) = 0.9891$

The probability of having exactly death is 0.9891

Answer:

k = 6.26

Step-by-step explanation:

Find the midpoint of each frequency range, multiply that number by the frequency, sum up and divide by the total frequency.

This will give the mean number.

The mean is:

[17*( 3 + 3.5)/2 + 21*(3.5 + k)/2 + 33*(k + 4)/2 + 54*(4 + 4.5)/2 + 15*(4.5 + 6)/2]/140 = 4.09
55.25 + 10.5k + 36.75 + 16.5k + 66 + 229.5 + 78.75 = 140*4.09
17k + 466.25 = 572.6
17k = 572.6 - 466.25
17k = 106.35
k = 106.35/17
k = 6.26

Note, I expected the value of k between 3.5 and 4. This is a bit of illogical outcome.
