Question: In a shipment of 10,000 of a certain type of electronic component, 300 are defective. Suppose that 50 components are selected at random for inspection, and let X denote the number of defective components found.

(a) The distribution of the random variable X is (choose one)

(i) binomial

(ii) hypergeometric

(iii) negative binomial

(iv) Poisson.

(b) Use R commands to find P(X ≤ 3).

(d) Using the approximate distribution, give an approximation to the probability P(X ≤ 3), and compare it with the exact probability found in part (b).
