Problem 11Multiple Choice
A study on screen habits and sleep patterns collected survey results from high school students aged 16 and older. The table below summarizes responses based on whether students used electronic devices right before bed and whether they reported poor sleep quality.
Find the probability that all three students reported poor sleep, given that they are selected from the group that did not use devices before bed. Assume the selections are made with replacement. Are the events independent?
