Answer:

ok so they test 7 components so the probity of getting a bad one for each is 0.2 so we just multiply this 7 times

0.2*0.2*0.2*0.2*0.2*0.2*0.2=0.0000128

Hope This Helps!!!

Assume that the number of messages input to a communication channel in an Exponential distribution with 7 messages arriving in a
NARA [144]

The probability that more than 3 messages will arrive during a 30-second interval is P(X=n)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^n}{n!}.

According to the statement

we have given that the an Exponential distribution with 7 messages arriving in a 10 second period and we have to find the probability that more than 3 messages will arrive during a 30-second interval.

So, For this purpose, we know that the

The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event.

And the given information is that :

3 messages will arrive during a 30-second interval.

Then

Probability = P(X=1) + P(X=2) + P(X=3).Then

The probability become according to the exponential distribution:

P(X=1)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^1}{1!}\\P(X=2)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^2}{2!}\\P(X=3)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^3}{3!}\\

And then substitute the values in it then

Probability = \dfrac{e^{-0.3 \times 20} (0.3 \times 20)^1}{1!}\ +\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^2}{2!}\ + \dfrac{e^{-0.3 \times 20} (0.3 \times 20)^3}{3!}\\

This is the probability.

So, The probability that more than 3 messages will arrive during a 30-second interval is P(X=n)=\dfrac{e^{-0.3 \times 20} (0.3 \times 20)^n}{n!}.

A student receives his grade report from a local community college, but the GPA is smudged. He took the following classes: a 2 h
Olin [163]

Answer:

  • C. 3.0

Step-by-step explanation:

<u>Lets calculate the points:</u>

  • Art - 2 hrs - B (3)                ⇒ 2*3 = 6 points
  • History - 3 hrs - A (4)         ⇒ 3*4 = 12 points
  • Science - 4 hrs - C (2)       ⇒ 4*2 = 8 points
  • Math - 3 hrs - B (3)            ⇒ 3*3 = 9 points
  • Lab - 1 hr - A (4)                 ⇒ 1*4 = 4 points

<u>Totals</u>

  • Total hours = 13            
  • Total points = 39

<u>GPA = total points/ total hours</u>

  • GPA = 39/13 = 3.0

Correct option is C

A quickie. If n identical dice are rolled, number of possible outcomes are?
nata0808 [166]
In rolling one die, there are 6 possible outcomes because each die has 4 faces. The number of outcomes when rolling n dice is equal to 6^n. By this, the number of outcomes when 2 dice are rolled is 36, 216 for 3 dice, and so on.
