Binomial Distribution Table: Symmetry Study the binomial distribution table (Table 2 of the Appendix). Notice that the
(a) Compare P(3 successes), where p = 0.30, with P(2 successes), where p = 0.70.
(b) Compare P(3 or more successes), where p = 0.30. with P(2 or fewer successes). where p = 0.70.
(c) Find the value of P(4 successes), where p = 0.30. For what value of r is P(r successes) the same using p = 0.70?
(d) What column is symmetric with the one headed by p = 0.20?
