Chapter 1: Weekly Math Games Recap
It’s thrilling to announce that we’ve completed our fourth round of Math Games, where participants had seven attempts to showcase their skills! Let’s extend a warm round of applause to our fearless and clever competitors!
1st Place: William Keens - 7 Points
2nd Place: Wotsit - 5 Points
3rd Place: Jonathan Lynn Harvey - 3 Points
Other Participants: ALQ, Neil Faver, Huub van Thienen, David Carnochan - 1 Point Each
Both William Keens and Wotsit presented the most straightforward solutions, while Jonathan Lynn Harvey and Huub van Thienen offered more complex approaches. Kudos to all for their efforts!
Here’s the solution:
To ensure that a number is chosen uniformly, each value within the designated range should have an equal chance of selection. This allows us to calculate the expected value by averaging the boundary values.
Alice’s Selection
The expected value for Alice’s selection is E = (0 + 1)/2 = 1/2.
Bob’s Selection
Bob's expected value is calculated as E = (1/2 + 2/3)/2 = 7/12.
This indicates that, over many selections, the average number picked by Alice and Bob would be 1/2 and 7/12, respectively. These values represent the central tendency of their selections.
Strategy for Carol
To enhance her winning chances, Carol should choose a number c such that 1/2 < c < 7/12. The goal is to identify a number that is equidistant from 1/2 and 7/12. We can achieve this by calculating the mean of these two numbers!
The solution is B!
How did you perform in the fourth round of Math Games? Looking forward to seeing you next week, challengers!
Tip me? I would be immensely grateful!
