So, if we start with logarithm ln(2) assuming a base of 10, how would I solve this without a calculator?
ln(2)
10^x = 2
And I get stuck there without a calculator. I could ..
ln(10^x) = ln(2)
x ln(10) = ln(2)
x = ln(2)
But that gets me back to where I started.
So, how would I go...
Lets start from the beginning ..
You pick a door at random.
There's a 2/3 chance of choosing the wrong door and a 1/3 chance of choosing the correct door.
If you chose one of the incorrect doors, there is left a correct and incorrect door.
They would flip the incorrect one.
Changing means you...
