please note that these questions need 100% correctness!

For questions 212-214, use the formula for a binomial probability distribution to find the indicated probabilities for the binomial random variable X. (Round your answers, as needed.)

212. P (X< 1) when n = 5, p = 0.2

213. P (X 1) when n = 5, p = 0.2

214. P (X> 8) when n = 10, p = 0.5

Progress on public health problems in a democratic society requires agreement about the mission and content of public health sufficient to serve as the basis for public action. There is no clear agreement among public decision-makers, public health workers, private sector health organizations and personnel, and opinion leaders about the translation of a broad view of mission into specific activities. As described inChapter 4, the governmental activities that can be described "public health" vary greatly among jurisdictions. This diversity reflects a wide variety of views about the appropriate scope of public health activities among the many publics that must support public health in the political process and through supportive activities in the private sector. Thus, it is difficult to build effective constituencies that extend beyond a particular issue to the support of broad purposes and the necessary continuing infrastructure of public health.
