I know that this is a true or false question, but I don't know the answer. I will have the answer in just a little bit.

I have the same answer as youtu for number 3. if you add red/blue as he posted to blue/red + red/red + blue/blue you get the total prob of 2 arrivals, which should be the case.

I find (1 - phi(1)). anyone else?

is Nn a random variable?

now i am reconsidering and got phi(1) p(Nn>n) = P(x1+..xn <cn) = P(Zn<1) central limit
