The arrivals of charged particles to a photodiode window is modeled as a exponential process with a mean of 5 nanoseconds. what is the probability that the time until the third arrival is 10 nanoseconds?

In an experiment you are to flip a two sided coin 100 times and record 55 heads up and 45 tails up determine the theoretical and experimental probability of getting a heads up in the experiment.

One expression below in undefined, and the other expression has a well defined value. which expression is undefined and explain why it has no value. which expression is defined? what is the value of that expression and how do you know? what is a different expression using a trig inverse function that is also undefined?
