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
