Answer:

Step-by-step explanation:

Use the laws of exponents, specifically the law for division.

When dividing, the exponents are subtracted.

For example, \frac{x^{8} }{x^{2} }=x^{8-2} =x^{6}

Now let's do an example where the exponent will equal zero.

\frac{5^{2} }{5^{2} } = 5^{2-2}=5^0=1

Now let's see why this equals 1. If you actually solve 5^2 it equals 25. So, let's solve the numerator and denominator and simplify.

\frac{5^{2} }{5^{2} } = \frac{25}{25} =1

As you can see, an exponent of 0 represents having the same number in the numerator and denominator, which when solved it equals 1.

Answer:

(a) The probability of more than one death in a corps in a year is 0.1252.

(b) The probability of no deaths in a corps over 7 years is 0.0130.

Step-by-step explanation:

Let <em>X</em> = number of soldiers killed by horse kicks in 1 year.

The random variable X\sim Poisson(\lambda = 0.62).

The probability function of a Poisson distribution is:

P(X=x)=\frac{e^{-\lambda}\lambda^{x}}{x!};\ x=0,1,2,...

(a)

Compute the probability of more than one death in a corps in a year as follows:

P (X > 1) = 1 - P (X ≤ 1)

             = 1 - P (X = 0) - P (X = 1)

             =1-\frac{e^{-0.62}(0.62)^{0}}{0!}-\frac{e^{-0.62}(0.62)^{1}}{1!}\\=1-0.54335-0.33144\\=0.12521\\\approx0.1252

Thus, the probability of more than one death in a corps in a year is 0.1252.

(b)

The average deaths over 7 year period is: \lambda=7\times0.62=4.34

Compute the probability of no deaths in a corps over 7 years as follows:

P(X=0)=\frac{e^{-4.34}(4.34)^{0}}{0!}=0.01304\approx0.0130

Thus, the probability of no deaths in a corps over 7 years is 0.0130.
