Thank you for the welcome. And thank you for such a fast reply too.
I have been reading and searching for days on ends that I have thought of asking for help as a last resort. But now, i realized, I need more reading and I really need to work harder.
Thank you very much and more power!

Hi!
I am currently taking Probability and Statistics subject at a university and I find your page very helpful. I actually find it more comprehensible than our discussions at the university. I would like to thank you for all these materials on probability and statistics. They have helped me a lot and I understood most of my lessons with your help.
However, I have a couple of problems which I did not find in any of the examples you have provided and I don`t know how to do them. Can you please take a look and help me solve and understand them?
Problem 1: The probability that a patient recovers from a rare blood disease is 0.4. If 15 people are known to have contracted this disease, what is the probability that
a. at least 10
Problem 2: On average a certain intersection results in 3 traffic accidents per month. What is the probability that for any given month at this intersection
a. exactly 5 accidents will occur?
b. less than 3 accidents will occur?
c. at least 2 accidents will occur?
I would greatly appreciate your help regarding my problem. Thank you very much and more power!
Sincerely,
Delsa
