Multiply conditional probabilities: $(5/12) \times (4/11) \times (3/10) = 1/22$.
Total marbles = $5 + 4 + 3 = 12$. The probability of drawing 3 red marbles sequentially without replacement is $\frac{5}{12} \times \frac{4}{11} \times \frac{3}{10} = \frac{60}{1320} = \frac{1}{22}$. Equivalently, $\frac{_5C_3}{_{12}C_3} = ...
