Minor earthquakes frequently occur in the Laurentians. Assume that the "waiting times" in days between earthquakes is exponentially distributed with PDF f(t) = 0.125e^-0.125t. What is the probability that the waiting time for the next earthquake will be at least 5 days?

I have started learning about vectors for A level and cant really remember anything about GCSE math.

I have to find an angle of 2 vectors. I have done the equation and am left with -1 / 6. The example says the answer is 99.6 and I am trying to figure out why?
