### Percentage of People Owning Smartphones or TabletsAccording to recent data:- 44.87% of people on earth have a smartphone.- 25.41% have a tablet.- 9% own both a smartphone and a tablet.Given these statistics, the question posed is: What percentage of people on earth own either a smartphone or a tablet?**Answer Choices**:1. 11.40%2. 61.28%3. 70.28%4. 79.28%To calculate this, we use the principle of inclusion and exclusion in set theory to find the total percentage of people who own a smartphone or a tablet.Using the formula:\[ P(A \cup B) = P(A) + P(B) - P(A \cap B) \]Where:- \( P(A) \) is the probability of owning a smartphone = 44.87%- \( P(B) \) is the probability of owning a tablet = 25.41%- \( P(A \cap B) \) is the probability of owning both a smartphone and a tablet = 9%\[P(A \cup B) = 44.87\% + 25.41\% - 9\% = 61.28\%\]Therefore, the percentage of people who own either a smartphone or a tablet is: **61.28%**Choose the correct option:1. 11.40%2. **61.28%**3. 70.28%4. 79.28%
