@Calvin Lin – I thought of using recurrence relations but couldn't. – Adarsh Kumar · 1 year, 7 months ago

@Adarsh Kumar – Hint: Try complementary probability. It makes it a bit easier to solve. And stars and bars. – Pi Han Goh · 1 year, 7 months ago

@Pi Han Goh – Thanks for the hint! – Adarsh Kumar · 1 year, 7 months ago
