You are on a two month training program with a group of Korean teachers of English.
There are 20 teachers, ranging in age between late 20s to early 50s.
How many of their grandmothers are likely to die during the course?
Consider the current months (October-November) as the timeframe. Assume the grandmothers are all residents of Daegu, Korea.
I probably cannot provide any more specifics than those, but if you want clarification I will try.
