Question

3. Nor expected to escape 3 classes in a week. Find the probability of she makes
a. no escape this week,
b. 4 escapes at most this week,
c. 3 escapes for the next two weeks.

Answer 1

are you supposed to use poisson distribution for this? if not, need some more information

Answer 2

expected value is 3, answer to the first question, making the rather broad assumption that she "escapes classes" in a poisson process, is \(e^{-3}\)
