Answer:
18.88% probability that three or four customers will arrive during the next 30 minutes
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
Average rate of 6.4 per 30 minutes.
This means that 
What is the probability that three or four customers will arrive during the next 30 minutes?
18.88% probability that three or four customers will arrive during the next 30 minutes
Answer:
Step-by-step explanation:
p - 4p + 8 = 7p - 14
-3p + 8 = 7p - 14
-10p + 8 = -14
-10p = -22
p = 22/10
p = 2.2
Answer:
It depends on how many colors there are like if there are 7 different colors, the possibility would be 100/7
Answer: 10/21
Step-by-step explanation:
From the question, we are told that two urns both contain green balls and red balls. Urn I contains 4 green balls and 8 red balls and Urn II contains 2 green balls and 5 red balls.
Urn 1 contains 4 green balls and 8 red balls. This means that the probability of drawing a red ball in urn 1 will be 8/12 = 2/3.
Urn II contains 2 green balls and 5 red balls. This means that the probability of drawing a red ball in urn 2 will be 5/7
Since we've the probability of drawing a red ball from both urns, we then multiply them together. This will be:
= 2/3 × 5/7
= 10/21
