Astudy of immunizations among school‑age children in california found that some areas had rates of unvaccinated school‑age children as high as 13.5% in 2014. imagine a classroom of 20 children in one such area where 13.5% of children are unvaccinated. if there are no siblings in the classroom, we are willing to consider the vaccination status of the 20 unrelated children to be independent. (a) obtain the probability that none of the 20 children in such a classroom would be unvaccinated. (enter your answer rounded to three decimal places.)
