In Exercises, assume that 400 births are randomly selected. Use subjective judgment to determine whether the given outcome is unlikely, and also determine whether it is unusual in the sense that the result is far from what is typically expected.
Exactly 111 girls.
Since probability of getting exactly 111 girls in randomly selected 400 births is very low so this event is unlikely. And since the outcome 111 girls is far below the number of girls we expect in 400 births (around 200 girls) so this is unusually low number of girls in 400 births. So the event of exactly 111 girls in 400 births is unlikely and unusually low.
