Answer:
0.048 is the probability that more than 950 message arrive in one minute.
Step-by-step explanation:
We are given the following information in the question:
The number of messages arriving at a multiplexer is a Poisson random variable with mean 15 messages/second.
Let X be the number of messages arriving at a multiplexer.
Mean = 15
For poison distribution,
Mean = Variance = 15

From central limit theorem, we have:
where n is the sample size.
Here, n = 1 minute = 60 seconds
P(x > 950)
Calculation the value from standard normal z table, we have,

0.048 is the probability that more than 950 message arrive in one minute.
Answer:
45/60=0.75
Step-by-step explanation:
The inequality the that is joined by and or or is called a Compound inequality. Compound inequality contains least two inequalities that are separated by either an or or. The graph to this inequality with an And represent intersection while the inequality that contains or represent the union.
Answer:
The answer is 1,043. (you could just use a calculator)
