Assume a Poisson random variable has a mean of 5 successes over a 125-minute period.

goldenfox [79]

Answer:

a

$\mu = 25$

b

$\lambda =0.04$

c

$P(X > 65 ) =0.0742$

Step-by-step explanation:

From the question we are told that

The number of success is n = 5

The time duration is N = 125 minutes

Generally the mean of the random variable is mathematically represented as

$\mu = \frac{N}{n}$

=> $\mu = \frac{125}{5}$

=> $\mu = 25$

Generally the rate parameter is mathematically represented as

$\lambda = \frac{1}{\mu}$

=> $\lambda = \frac{1}{25}$

=> $\lambda =0.04$

Generally the cumulative distribution function for exponential distribution function is

$F(x) = \left \{0 \ \ \ \ \ \ x \le 0}} \atop {1 -e^{-\lambda t }\ x>0}} \right.$

Generally the probability that the time to success will be more than 63 minutes is mathematically represented as

$P(X > 65 ) = 1 - P(X \le 65)$

Here

$P(X \le 65) = 1 -e^{-65 * \lambda }$

=> $P(X \le 65) = 1 -e^{-65 * 0.04 }$

=> $P(X \le 65) = 0.92573$

So

$P(X > 65 ) = 1 - 0.92573$

$P(X > 65 ) =0.0742$

This is what is known as a derangement - an arrangement in which none of the objects maintain their original position.
For example, with the numbers, 1234, in how many ways can they be arranged so that 1 is NOT in first position, 2 is NOT in second position, etc.
Of the 24 possible permutations of four numbers, there are nine possible derangements:
