15) Stephanie has 10 cards numbered 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. What is the probability that she will pick a number less than 7?

1. ¹/₅
2. ¹/₄
3. ²/₃
4. ³/₅
5. ³/₈

Of the 10 cards, 1, 2, 3, 4, 5, and 6 will meet the criteria of being less than 7. Therefore, there is a 6 out of 10 probability of picking a card lower than 7. When reduced, this becomes 3/5.
