Q. Solve by the method of your choice.Twenty-two people purchase raflle tickets. Three winning tickets are selected at random. If first prize is $1000, second price is $500, and third prize is $100, in how many different ways can the prizes be awarded?There are different ways in which the prizes can be awarded.(Simplify your answer.)
Determine Number of Ways: We need to determine the number of ways to award three distinct prizes to three people out of 22. This is a permutation problem because the order in which the prizes are awarded matters (first, second, and third are distinct).
Select First Prize Winner: First, we select a winner for the first prize. There are 22 possible people who could win this prize.
Select Second Prize Winner: After awarding the first prize, we have 21 remaining people who could win the second prize.
Select Third Prize Winner: Finally, after awarding the second prize, we have 20 remaining people who could win the third prize.
Calculate Total Number of Ways: To find the total number of ways the three prizes can be awarded, we multiply the number of choices for each prize together: 22 choices for the first prize, 21 choices for the second prize, and 20 choices for the third prize.
Perform Multiplication: The calculation is 22×21×20.
Final Result: Performing the multiplication gives us 22×21×20=9240.
Final Result: Performing the multiplication gives us 22×21×20=9240.Therefore, there are 9240 different ways the three prizes can be awarded.
