The computer that controls a bank's automatic teller machine crashes a mean of 0.6 times per day. What is the probability that, in any seven-day week, the computer will crash less than 3 times? Round your answer to four decimal places.

0.2103 = 21.03% 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 interval.

Mean of 0.6 times a day

7 day week, so

What is the probability that, in any seven-day week, the computer will crash less than 3 times? Round your answer to four decimal places.

In which

So

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.
