I think there isn't enough information to be able to solve this problem. We need probability distribution function to know about the probability of getting 2 calls in following 2 minutes.

By Poisson distribution $$\lambda = 8$$ calls per two minutes.

So the answer on 1. is

$$P(X < 2) =0.003019$$

The answer on 2. is $$4$$ (average number of calls in any minute is $$4$$).
