Assume that during each second, a job arrives at a webserver with probability 0.03. Use the Poisson distribution to estimate the
Savatey [412]

Answer:

The probability that at lest one job will be missed in 57 second is=1- e^{-1.71} =0.819134

Step-by-step explanation:

Poisson distribution:

A discrete random variable X having the enumerable set {0,1,2,....} as the spectrum, is said to be Poisson distribution.

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

λ is the average per unit time

Given that, a job arrives at a web server with the probability 0.03.

Here λ=0.03, t=57 second.

The probability that at lest one job will be missed in 57 second is

=P(X≥1)

=1- P(X<1)

=1- P(X=0)

=1-\frac{e^{-1.71}(1.71)^0}{0!}

=1- e^{-1.71}

=0.819134

Explain multi step equations
Mice21 [21]
Multi-step equations are equations that  require more than one step to solve.

For example:
2x+6 = 10          You subtract 6 from both sides
2x= 4                 Divide both sides by 2
x=2                    It took 2 steps to solve for x, so it is a muti-step equation.

One step equation:
2x =6                divide 2 by both sides
x=3                    It only took one step, so it is an one-step equation.

Hope this can help you! Please put branliest answer if you like it!
