Outline Review of Probability Sampling A Special PMF Basic Plotting in R The Lab Assignment # 2 Deﬁnition The type of random sampling where diﬀerent outcomes have diﬀerent probability of occurring is referred to as probability sampling . Probability sampling is always sampling with replacement. Example Consider rolling a die twice and record the number of times 6 occurs. Describe an equivalent probability sampling experiment. Solution. The experiment that records the number of 6s can be thought of as a probability sampling experiment from the sample space population S = { 0 , 1 , 2 } , with probabilities P (0) = 25 / 36 , P (1) = 10 / 36 and P (2) = 1 / 36 .
