Find a counterexample to show that the following statement is false. The sum of two five-digit numbers is a six-digit number + i

Andrej [43]

Answer:

It not necessary that every time the sum of two five digit number is a six digit number.

Step-by-step explanation:

We are given the statement that sum of two five digit numbers is always a six digit number.

We have to give a counter example to show that the given statement is false.

It not necessary that every time the sum of two five digit number is a six digit number.

Example:

10,000 + 30,000 = 40,000

13,245 + 74,632 = 87,877

56463 + 26230 = 82693

50,000 + 50,000 = 1,00,000

The number of failures of a testing instrument from contamination particles on the product is a Poisson random variable with a m

Mazyrski [523]

Answer:

The probability that the instrument does not fail in an 8-hour shift is $P(X=0) \approx 0.8659$

The probability of at least 1 failure in a 24-hour day is $P(X\geq 1 )\approx 0.3508$

Step-by-step explanation:

The probability distribution of a Poisson random variable X representing the number of successes occurring in a given time interval or a specified region of space is given by the formula:

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

Let X be the number of failures of a testing instrument.

We know that the mean $\mu = 0.018$ failures per hour.

(a) To find the probability that the instrument does not fail in an 8-hour shift, you need to:

For an 8-hour shift, the mean is $\mu=8\cdot 0.018=0.144$

$P(X=0)=\frac{e^{-0.144}0.144^0}{0!}\\\\P(X=0) \approx 0.8659$

(b) To find the probability of at least 1 failure in a 24-hour day, you need to:

For a 24-hour day, the mean is $\mu=24\cdot 0.018=0.432$

$P(X\geq 1 )=1-P(X=0)\\\\P(X\geq 1 )=1-\frac{e^{-0.432}0.432^0}{0!}\\\\P(X\geq 1 )\approx 0.3508$
