The Bernoulli and Binomial probability distribution models are often very good models of patterns of occurrence of binary (“yes/no”) events that are of interest in public health; eg - mortality, disease, and exposure. Bernoulli distribution and Bernoulli trials apply to many other real life situations, eg., (1)Toss outcome of a coin (\H" vs. \T") (2)Workforce status in women (\In workforce" vs. \Not in workforce") (3)Education level in adults (\ 12 yrs." startxref
