Calculate the number of permutations and combinations using the formulas to confirm your answers above. 5. The Powerball lottery game uses 49 numbered balls in one drum and 42 numbered balls in the Powerball drum. Five balls are selected at random from the drum with 49, and one is made from the Powerball drum. How many selections are possible?

Bonus question: How many ways can you get 3 balls correct from the drum of 49 and the Powerball correct? [ Prizes will be awarded! ]...
