he average number of children a Japanese woman has in her lifetime is 1.37. Suppose that one Japanese woman is randomly chosen.

Question

Find the probability that she has no children.

Find the probability that she has fewer children than the Japanese average.

Find the probability that she has more children than the Japanese average. 

Answer 1

You need a standard deviation of the population and/or the type of distribution. The last two questions are approximately 50%, but, given that you can assume no partial children, the number will not be exact.
