A radioactive sample is counted for 1 minute and produces 900 counts. The background is counted for 10 min and produces 100 counts. Find the net count rate, the net standard deviation and the net uncertainty. (p. 138)
WebIn this section, you will learn how to quantify the relative frequency of occurrences of uncertain events by using probability models. You will learn about the measures of frequency, severity, likelihood, statistical distributions, and expected values. You will use examples to compute these values.
