In a family with 3 children, the probability that all the children are girls is appoximately 0.125. In a random sample of 1000 families with 3 children, what is the approximate probability that 95 or fewer will have 3 girls? Approximate a binomial distribution with a normal distribution 囲Click the icon to view the area under the standard normal curve table. The probability that 95 or fewer families will have 3 girls is (Round to four decimal places as needed.)
