Calculations Using the Binomial Tables for p Greater than 0.5

Many binomial tables onlytabulate symmetries up to 0.5. This does not mean we cannot use thebinomial tables for any value of p greater than 0.5 – only thatsome manipulation is involved. The manipulation rests onthatrepresentsthe probability of success in most textbooks.thenrepresents the probability of failure. Ifthenandwe can use the tables with values of
