To examine practices towards a pandemic otubreak, the researcher examined the relevant responses from the survey and assigned scores of 1 (below required standard), 2 (poor standards), 3 (satisfactory standards), 4 (meets required standards) and 5 (exceeds required standard) to each respondent. Using X to represent the score for practices against a pandemic outbreak, the probability distribution of X is shown in Table 3 below. x 1 2 3 4 5 P(X=x) 0.21 0.197 0.2 0.173 0.22 The researcher is interested in using the information in Table 3 to determine the probability that, from a sample of 10 randomly selected adults, exactly 3 of them exceeds the required standard for practices towards a pandemic outbreak. (a) identifying a suitable probability distribution to be used to find the probability that exactly three (3) adults, out of 10, exceeds the required standard for practices towards a pandemic outbreak. State the value(s) of the parameter(s) for this distribution.(b) justifying the suitability of the probability distribution identified in part (a)
