Hello there! Your answer would be !
You can't fit 24 directly into 7 nor can you divide 24 by 7, so you have to use the biggest number inside of 24 that divides into 7. This number would be 21. Pull 21 out of the fraction and divide it by 7, you get 3. You will still have 3/7 left over. You can't do anything with this, so your final answer is .
Hope this helps, have a great day!

Complete Question
The Brown's Ferry incident of 1975 focused national attention on the ever-present danger of fires breaking out in nuclear power plants. The Nuclear Regulatory Commission has estimated that with present technology there will be on average, one fire for every 10 years for a reactor. Suppose that a certain state has two reactors on line in 2020 and they behave independently of one another. Assuming the incident of fires for individual reactors can be described by a Poisson distribution, what is the probability that by 2030 at least two fires will have occurred at these reactors?
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The rate at which fire breaks out every 10 years is
Generally the probability distribution function for Poisson distribution is mathematically represented as
Here x represent the number of state which is 2 i.e
Generally the probability that by 2030 at least two fires will have occurred at these reactors is mathematically represented as
