###### Question details

Table 4-1 describes the probability distribution for the number of girls among 14 randomly selected newborn babies. Assuming that we repeat the study of randomly selecting 14 newborn babies and counting the number of girls each time, find the mean number of girls (among 14), the variance, and the standard deviation. Use those results and the range rule of thumb to find the maximum and minimum usual values.

1) What is the probability of 8 or more girls in 14 births?

2)Is the probability of having 8 or more girls in 14 births unusual?
