AboutScott A Wilson Expertise Most ordinary differential equations.
Experience I have taken Differential Equations at OSU.
Occasionally I have assisted people with questions on the subject.
Publications In the paper where MS students publish a thesis on shock waves and rarefaction fans.
Education/Credentials MS at OSU in Mathemematics.
MS at OSU in Mathematical Science.
Awards and Honors Graduation with honors for my BS and MS.
Past/Present Clients I answered many questions at OSU, down in south seattle at a college, at a church in Corvallis, OR,
as Safeway in Washington, and many other areas. I have had several thousand right here.
Question In a certain plant there are on an average 4 accidents per month.Find the probability that in a given year there will be less than 4 accidents
Answer This sounds like an exponential distribution with L=1/4 where L is for lambda.
Since the distribution is f(x) = Le^(-Lx),
the cumulative distribution is 1 - e^(-Lt) for x being between 0 and t.
The answer, since we are looking for x to be between 0 and 4, is 1 - e^(-4/4) = 1 - 1/e.
