Answer:
Step-by-step explanation:
Add all paper clip sizes together:
They want the probability of either a small or medium being chosen, so you add both paper clips sizes together.
Now put the number of small and medium paper clips together over the total number of paper clips to find the probability.
Can divide 350 and 500 by 50, which simplifies it down to 7/10.
Answer:
0.67% probability he will have to shut down after this month
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.
On average sells 8.9 machines per month.
So
Using the Poisson distribution, what is the probability he will have to shut down after this month
If he sells less than 3 machines.
0.67% probability he will have to shut down after this month
