Question 354691
seventy percent of all children in a school do not have cavities. From the binomial probability distribution table, the probability that in a random sample of eleven children selected from the school that at least 7 will not have cavities is:
-----------
P(7<= x <= 11) = 1 - binomcdf(11,0.7,6) = 0.8000
