Problem
A card is drawn randomly from 10 cards numbered from 1 to 10 then the Probablity of the drawn card carry a number less than 3 equals
Solution
Step 1 ：\( P(E) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}} \)
Step 2 ：\( P(E) = \frac{2}{10} \)
Step 3 ：\( P(E) = \frac{1}{5} \)
