An angle with a known true value was measured $50$ times by a measuring teamand the average error of the unit$-$weighted measurement was calculated as m$=$ plus$/$minus $4^($cc$)\mathrm{.}5.$ Relative frequencies and numbers of errors with epsilon $=1^($cc$)$ and epsilon $=3^($cc$)$ determine?

Hint $($p ucu$)$: The Gaussian error function will be used in the solution.
