Gcompare the binomial and hypergeometric distributions by plotting their probability distributions in the same figures. let’s say we have a population of n = 50 items, of which r = 9 are considered failures. we sample n of these items randomly. the random variable x is the number of failures among those n sampled items. you need to plot the probability mass function fx(x) for every possible value of x, for the following cases: (a) if we sample n = 20 items, plot both the true hypergeometric distribution and the corresponding binomial distribution (which is just an approximation here). hint: for the binomial, you need to take the probability p = r=n. (b) if we sample n = 3 items, produce the same plots. what can you say about your results? hint: since i asked about the probability distribution (or mass function), you should not perform any random sampling here { you should simply plot the equation for the probability distribution.

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
