Question 1093587: Researchers at the University of Pennsylvania School of Medicine have determined that children under 2 years old who sleep with the lights on have a 39% chance of becoming myopic before they are 16. Children who sleep in darkness have a 22% probability of becoming myopic. A survey indicates that 23% of children under 2 sleep with some light on. Find the probability that a random child under 2 will become myopic before reaching 16 years old.

You can put this solution on YOUR website! Take 1000 children
=======Myopic========not myopic====total
Dark=====169.4==========600.6=======770
Light=====89.7==========140.3======= 230
Total=====259.1=========740.9======1000
A random child will become myopic 259.1/1000 times or 25.9%. It is closer to the dark results because most of the children sleep in the dark.
