so I've got this question:
A die with faces numbered 1 to 6 is biased so that , (r=1,...,6). Find the value of k.
Now my problem is i don't know which numbers it is biased to. supposing that (r=1,...,6) means the numbers from 1 to 6.
Thanks
Hello, arze!
You have to understand what was given.
A die with faces numbered 1 to 6 is biased so that
Find the value of
We are told that the probability of rolling a number is a constant times
So we have these probabilities:
. . . .
The probability that one of the numbers turn up is 100%.
So we have: .
Therefore: .
