Answer
Explanation:
Step1: Calculate number of students who play video games
The total number of students is 150, and the fraction of students who play video games is $\frac{2}{3}$. So the number of students who play video games is $150\times\frac{2}{3}=100$.
Step2: Calculate number of students who do not play video games
The number of students who do not play video games is $150 - 100=50$.
Step3: Calculate number of video - game - playing students who do not use social media
The number of video - game - playing students who use social media is 85. So the number of video - game - playing students who do not use social media is $100 - 85 = 15$.
Step4: Calculate number of non - video - game - playing students who do not use social media
The percentage of non - video - game - playing students who do not use social media is 20%. So the number of non - video - game - playing students who do not use social media is $50\times0.2 = 10$.
Step5: Calculate number of non - video - game - playing students who use social media
The number of non - video - game - playing students who use social media is $50-10 = 40$.
Step6: Calculate total number of students who use social media
The total number of students who use social media is $85 + 40=125$.
Step7: Calculate total number of students who do not use social media
The total number of students who do not use social media is $15 + 10=25$.
