I am trying to understand what is the implied distribution of the following problem: A student asks for help from the professor 2 times per test on average. the student took 5 different test
a) what is the probability that at only 2 tests the student didn't ask from help at all
b) the probability that in 3 tests at the most the student asked for help only 3 times
I know that if Poisson distribution is not specified then it cant be assumed. I am at a loss on this one. Help will be appreciated.
Edit: How would i solve it assuming Poisson distribution?
