Answer:
0.3216 = 32.16% probability that, in any seven-day week, the computer will crash less than 3 times
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
Mean of 0.5
7-day week, so 
What is the probability that, in any seven-day week, the computer will crash less than 3 times?

In which





0.3216 = 32.16% probability that, in any seven-day week, the computer will crash less than 3 times
You could find this by going and doing:
<span>9: 9,18,27,36,45,54,63,72...
12:12,24,36,48,60,72...
</span>36 is the first # that pops up so you could do 36 as a common denominator
Answer:
A) $4,905 B) $5,310
Step-by-step explanation:
To get the answer, just simply add the amount by the percentage.
4,500 + 9% = A
For 2 years, just do 9 x 2 = 18 because it's 2 years
4,500 + 18% = B
No, she did not substitute the correct x and y values :)
