Say I have a wallet that contained either a $2 bill or a $20 bill (with equal likelihood), but I don’t know which one. I add a $

2 bill. Later, I reach into my wallet without looking and remove a bill. It’s a $2 bill. There’s one bill remaining in the wallet. What is the chances that it’s a $2 bill?

Answer:

        \large\boxed{\large\boxed{2/3}}

Explanation:

The initial scenary is:

  • One $2-bill with 50% probability
  • One $20-bill with 50% probability

I will call the original $2-bill $2a and the $2-bill that I add $2b-bill.

When $2b-bill is added the options are:

  • One $2a-bill plus $2b-bill with 50% probability
  • One $2b-bill plus one $20-bill 50% probability

When I remove one of the $2 bills there are three possibilities for the bills on the wallet:

  • One $2a-bill,
  • One $2b-bill, and
  • One $20-bill

Each option is equally likely. Then each option has probability 1/3.

Two of those options are a $2 bill ($2a-bill and $2b-bill).

Hence, the probability of the bill remaining in the wallet be a $2 bill is 1/3 + 1/3 = 2/3.

svet-max [94.6K]

The average return of the stock is 10%.

The average risk-free rate is 7%.

=(0.10-0.07)/1.5

=0.03/1.5

=0.02

So, the Treynor index for the stock will be 0.02.
