Answer:
The probability that more than 7 weeks pass between accidents is 4.0551 .
Step-by-step explanation:
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes
A Poisson distribution is a probability distribution that is used to show how many times an event is likely to occur over a specified period.
mean = 5 weeks
rate = 1/5 = 0.2
x = average time
P(x > 7) = e^(0.2×7) = 4.0551
The probability that more than 7 weeks pass between accidents is 4.0551 .
