Hi, Could anyone please explain how to solve this type of question: In a ski resort, the probability of more than 3 accidents in any day at the weekend (Saturday and Sunday) is 0.24. Assuming a Poisson model, 1) Calculate the mean number of accidents per day at the weekend (Saturday and Sunday) I got to the point that P(x>3) =0.24 and P(x<3 or x=3) = 0.76. How do I continue from here? I also know that the answer is 2.49. 2) Calculate the probabilit that, in the four weekends in February, there will be more than 5 accidents during at least two of t

Hey guys So now I have decided for my math IA i'm gonna explore Poisson Distribution. We haven't cover the topic so far (probably won't until next semester ) but i'm doing it anyways. But I have NO CLUE how to approach that my IA. I'm thinking to investigate something about genetic mutation using the distribution, or probably something relate to bio area. But don't know how? Should I use real-life example or should I make up one on my own?? Also for one problem on genetic mutation is it going to take me to 10 pages?? HOW should I do this Math HL Genius PPL? THANKS!

Hi guys, do we need do know and calculate poisson distribution for the exam tomorrow ? (For Mathematics Standard Level / Syllabus 2014) Thanks in advance, G.

The fish in a lake have weights that are normally distributed with a mean of 1.3 kg and a standard deviation of 0.2 kg. a) determine the probability that a fish that is caught weighs less than 1.4 kg. I'm not sure how to even approach this problem. I don't know how to use the mean and the standard deviation to be able to gain at least a p value that i can use t do the binomial distribution.
