Math help?
I want to make sure I’m doing these right:
As a reward for selling the most raffle tickets, Lars gets to pick 4 CDs from a list of 25 CDs. How many different combinations are possible?
In how many ways can 6 trophies be chosen for a display from a collection of 15 trophies?
A circular dartboard is divided into 20 equally sized sections numbered from 1 to 20. What is the probability that 2 randomly thrown darts will both land on 5? (Assume that it is equally likely for a dart to land on any of the 20 sections.)
Can you help me?
1. 25C4 = 12,650
2. 15C6 = 5,005 ==> I am assuming the trophies, when displayed, their order doesn’t matter.
3. 1/20 * 1/20 = 1/400 = 0.0025
