Question

Can playing video games as a child and teenager lead to a gambling or substance addiction? According to the April 11, 2009, USA Today article “Kids show addiction symptoms,” research published in the Journal Psychological Science found that 8.5% of video-game playing children and teens displayed behavioral signs that may indicate addiction. Suppose a randomly selected group of 30 video-gaming eighth-grade students is selected.
a. What is the probability that exactly 2 will display addiction symptoms?
b. If the study also indicated that 12% of video gaming boys display addiction symptoms, what is the probability that exactly 2 out of the 17 boys in the group will display addiction symptoms?
c. If the study also indicated that 3% of video-gaming girls display addiction symptoms, what is the probability that exactly 2 out of the 13 girls in the group will display addiction symptoms?
